Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612566, here are decompositions:

19 + 31612547 = 31612566
53 + 31612513 = 31612566
79 + 31612487 = 31612566
113 + 31612453 = 31612566
137 + 31612429 = 31612566
197 + 31612369 = 31612566
257 + 31612309 = 31612566
367 + 31612199 = 31612566

Showing the first eight; more decompositions exist.
