Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612682, here are decompositions:

19 + 31612663 = 31612682
61 + 31612621 = 31612682
109 + 31612573 = 31612682
151 + 31612531 = 31612682
229 + 31612453 = 31612682
313 + 31612369 = 31612682
331 + 31612351 = 31612682
373 + 31612309 = 31612682

Showing the first eight; more decompositions exist.
