Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517336, here are decompositions:

139 + 31517197 = 31517336
457 + 31516879 = 31517336
547 + 31516789 = 31517336
607 + 31516729 = 31517336
709 + 31516627 = 31517336
733 + 31516603 = 31517336
769 + 31516567 = 31517336
853 + 31516483 = 31517336

Showing the first eight; more decompositions exist.
