Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517476, here are decompositions:

59 + 31517417 = 31517476
83 + 31517393 = 31517476
233 + 31517243 = 31517476
269 + 31517207 = 31517476
449 + 31517027 = 31517476
503 + 31516973 = 31517476
587 + 31516889 = 31517476
719 + 31516757 = 31517476

Showing the first eight; more decompositions exist.
