Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612326, here are decompositions:

13 + 31612313 = 31612326
17 + 31612309 = 31612326
19 + 31612307 = 31612326
103 + 31612223 = 31612326
127 + 31612199 = 31612326
257 + 31612069 = 31612326
283 + 31612043 = 31612326
313 + 31612013 = 31612326

Showing the first eight; more decompositions exist.
