Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517366, here are decompositions:

373 + 31516993 = 31517366
487 + 31516879 = 31517366
547 + 31516819 = 31517366
577 + 31516789 = 31517366
613 + 31516753 = 31517366
733 + 31516633 = 31517366
739 + 31516627 = 31517366
823 + 31516543 = 31517366

Showing the first eight; more decompositions exist.
