Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508824, here are decompositions:

167 + 31508657 = 31508824
173 + 31508651 = 31508824
257 + 31508567 = 31508824
317 + 31508507 = 31508824
461 + 31508363 = 31508824
593 + 31508231 = 31508824
647 + 31508177 = 31508824
653 + 31508171 = 31508824

Showing the first eight; more decompositions exist.
