Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499764, here are decompositions:

3 + 31499761 = 31499764
53 + 31499711 = 31499764
227 + 31499537 = 31499764
353 + 31499411 = 31499764
467 + 31499297 = 31499764
701 + 31499063 = 31499764
743 + 31499021 = 31499764
761 + 31499003 = 31499764

Showing the first eight; more decompositions exist.
