Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508410, here are decompositions:

47 + 31508363 = 31508410
179 + 31508231 = 31508410
233 + 31508177 = 31508410
239 + 31508171 = 31508410
251 + 31508159 = 31508410
257 + 31508153 = 31508410
317 + 31508093 = 31508410
383 + 31508027 = 31508410

Showing the first eight; more decompositions exist.
