Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617502, here are decompositions:

5 + 31617497 = 31617502
41 + 31617461 = 31617502
53 + 31617449 = 31617502
71 + 31617431 = 31617502
89 + 31617413 = 31617502
131 + 31617371 = 31617502
173 + 31617329 = 31617502
233 + 31617269 = 31617502

Showing the first eight; more decompositions exist.
