Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612422, here are decompositions:

31 + 31612391 = 31612422
41 + 31612381 = 31612422
53 + 31612369 = 31612422
59 + 31612363 = 31612422
71 + 31612351 = 31612422
109 + 31612313 = 31612422
113 + 31612309 = 31612422
181 + 31612241 = 31612422

Showing the first eight; more decompositions exist.
