Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617814, here are decompositions:

3 + 31617811 = 31617814
17 + 31617797 = 31617814
101 + 31617713 = 31617814
227 + 31617587 = 31617814
251 + 31617563 = 31617814
281 + 31617533 = 31617814
311 + 31617503 = 31617814
317 + 31617497 = 31617814

Showing the first eight; more decompositions exist.
