It is studied in first place the function s(t)=\sum\sum \log p_1 \log p_2, where the sum is extended for all prime numbers pi such that p_1^m+p_2^n=t. Are proved formulas (14) and(26), which express its value in terms of Chebyshev’s function \psi(x). In this way is obtained formula (38), that gives the asymptotic value of s(t) with a new ”singular” series which runs through the zeros of the Zeta function, but that at present can not be evaluated in a sufficiently accurate form. In second place, for the function \nu(t)=\sum\sum \log p_1 \log p_2 (with p_1+p_2=t), already considered by Hardy-Littlewood in ”Partitio Numerorum III” (P.N.III), is proved the exact formula \frac{\nu(t+0)+\nu(t-0)}{2} = \Delta^{2)}

    where \Delta^{2)}^ = second difference;
    \mathcal{L} and \mathcal{L}^{-1} are the direct and inverse Laplace transforms;
    \nu(x) = \sum \log p (p \leq x)

The circle method applied in P.N.III is equivalent to determine \mathcal{L}^{-1} through the complex inversion formula along a Bromwich contour. But it is evident that is much preferable to employ tables of direct and inverse transforms because the functions in­volved are elementary; because is obtained an exact expression for the remainder, and because all the calculus is by far more simple. One arrive thus to the inconditional formula (130), which very closely resembles the famous conjecture A of P.N.III.
