  I define Goldbach counting function with N > 0 and square-free P > 0.
Decomposition of this function is discovered and deduction formula is found. I
propose a hypothesis on upper bound of Goldbach counting function and prove
that Goldbach conjecture is true under this hypothesis. Also, I propose a
second hypothesis on upper bound of Goldbach counting function and prove that
the twin prime conjecture is true under this hypothesis
