Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612652, here are decompositions:

31 + 31612621 = 31612652
79 + 31612573 = 31612652
139 + 31612513 = 31612652
199 + 31612453 = 31612652
223 + 31612429 = 31612652
229 + 31612423 = 31612652
271 + 31612381 = 31612652
283 + 31612369 = 31612652

Showing the first eight; more decompositions exist.
