We consider the ternary Goldbach problem with two prime variables of the form k 2 + m 2 + 1 and find an asymptotic formula for the number of its solutions. Notations. ByGreek letters we denote real numbers and by small Latin letters -integers. However, the letter p, with or without subscripts, is reserved for primes. By ε we denote an arbitrarily small positive number, not the same in different appearances. N is a sufficiently large odd integer and L = log N. We denote by J the set of all subintervals of the interval [1, N] and if J 1 , J 2 ∈ J then J = J 1 , J 2 is the corresponding ordered pair. Respectively k = k 1 , k 2 is two-dimensional vector with integer components k 1 , k 2 and, in particular, 1 = 1, 1 . We write (m 1 , . . . ,m k ) for the greatest common factor of m 1 , . . . ,m k . As usual τ (k) is the number of positive divisors of k; r(k) is the number of solutions of the equation m 2 1 + m 2 2 = k in integers m j ; ϕ(k) is the Euler function; Ω(k) is the number of the prime factors of k, counted with the multiplicity; χ (k) is the non-principal character modulo 4 and L(s, χ ) is the corresponding Dirichlet's L-function. We mark by an end of a proof, or its absence.

“…Thus, it follows from formulas (2.18) and (2.19) and from the main 1emma that Furthermore, we find the asymptotics of A(n), which already is a ternary problem that can be solved by the Hooly lemma concerning the distribution of quasiprlme numbers in arithmetic progressions. Let us apply the sharpened version of this lemma (Lemma 3 of the paper [6] The proof of Theorem 2 is completed by the calculation of the inner sums in (2.25) by means of Lemma 2.3.2 of the paper [7] (we apply a modified version of this lemma that can be proved similarly). Finally we have where R is a fixed genus defined by the given form ~(u, v).…”

“…Taking c x = 2 in the Lemma, and G > B (2), we see that f Actually, it will be clear from the sequel that the weaker condition f(p")<l suffices for the purpose of estimating effectively the sums JSJ and <S 2 . Hence, if also / is nonnegative, the method will be seen to lead, under these alternative conditions on/, to good lower bounds for 8.…”
