Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613326, here are decompositions:

83 + 31613243 = 31613326
587 + 31612739 = 31613326
593 + 31612733 = 31613326
599 + 31612727 = 31613326
659 + 31612667 = 31613326
743 + 31612583 = 31613326
839 + 31612487 = 31613326
1013 + 31612313 = 31613326

Showing the first eight; more decompositions exist.
