Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517354, here are decompositions:

157 + 31517197 = 31517354
373 + 31516981 = 31517354
577 + 31516777 = 31517354
601 + 31516753 = 31517354
727 + 31516627 = 31517354
751 + 31516603 = 31517354
787 + 31516567 = 31517354
811 + 31516543 = 31517354

Showing the first eight; more decompositions exist.
