Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511702, here are decompositions:

151 + 31511551 = 31511702
163 + 31511539 = 31511702
199 + 31511503 = 31511702
421 + 31511281 = 31511702
613 + 31511089 = 31511702
631 + 31511071 = 31511702
661 + 31511041 = 31511702
709 + 31510993 = 31511702

Showing the first eight; more decompositions exist.
