Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613396, here are decompositions:

13 + 31613383 = 31613396
19 + 31613377 = 31613396
277 + 31613119 = 31613396
457 + 31612939 = 31613396
523 + 31612873 = 31613396
643 + 31612753 = 31613396
733 + 31612663 = 31613396
769 + 31612627 = 31613396

Showing the first eight; more decompositions exist.
