Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612536, here are decompositions:

5 + 31612531 = 31612536
23 + 31612513 = 31612536
83 + 31612453 = 31612536
107 + 31612429 = 31612536
113 + 31612423 = 31612536
167 + 31612369 = 31612536
173 + 31612363 = 31612536
223 + 31612313 = 31612536

Showing the first eight; more decompositions exist.
