Theorem bgoldbtbnd

Description: If the binary Goldbach conjecture is valid up to an integer N , and there is a series ("ladder") of primes with a difference of at most N up to an integer M , then the strong ternary Goldbach conjecture is valid up to M , see section 1.2.2 in Helfgott p. 4 with N = 4 x 10^18, taken from OeSilva, and M = 8.875 x 10^30.
