Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517268, here are decompositions:

37 + 31517231 = 31517268
61 + 31517207 = 31517268
71 + 31517197 = 31517268
229 + 31517039 = 31517268
241 + 31517027 = 31517268
257 + 31517011 = 31517268
317 + 31516951 = 31517268
379 + 31516889 = 31517268

Showing the first eight; more decompositions exist.
