Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612634, here are decompositions:

7 + 31612627 = 31612634
13 + 31612621 = 31612634
37 + 31612597 = 31612634
61 + 31612573 = 31612634
103 + 31612531 = 31612634
181 + 31612453 = 31612634
211 + 31612423 = 31612634
271 + 31612363 = 31612634

Showing the first eight; more decompositions exist.
