Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508514, here are decompositions:

5 + 31508509 = 31508514
7 + 31508507 = 31508514
53 + 31508461 = 31508514
61 + 31508453 = 31508514
71 + 31508443 = 31508514
97 + 31508417 = 31508514
151 + 31508363 = 31508514
227 + 31508287 = 31508514

Showing the first eight; more decompositions exist.
