Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627118, here are decompositions:

67 + 31627051 = 31627118
139 + 31626979 = 31627118
151 + 31626967 = 31627118
277 + 31626841 = 31627118
331 + 31626787 = 31627118
409 + 31626709 = 31627118
499 + 31626619 = 31627118
547 + 31626571 = 31627118

Showing the first eight; more decompositions exist.
