Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508692, here are decompositions:

11 + 31508681 = 31508692
41 + 31508651 = 31508692
53 + 31508639 = 31508692
71 + 31508621 = 31508692
113 + 31508579 = 31508692
239 + 31508453 = 31508692
461 + 31508231 = 31508692
521 + 31508171 = 31508692

Showing the first eight; more decompositions exist.
