Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617910, here are decompositions:

11 + 31617899 = 31617910
47 + 31617863 = 31617910
83 + 31617827 = 31617910
113 + 31617797 = 31617910
197 + 31617713 = 31617910
251 + 31617659 = 31617910
281 + 31617629 = 31617910
347 + 31617563 = 31617910

Showing the first eight; more decompositions exist.
