Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517246, here are decompositions:

3 + 31517243 = 31517246
97 + 31517149 = 31517246
367 + 31516879 = 31517246
457 + 31516789 = 31517246
547 + 31516699 = 31517246
577 + 31516669 = 31517246
613 + 31516633 = 31517246
619 + 31516627 = 31517246

Showing the first eight; more decompositions exist.
