Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617610, here are decompositions:

23 + 31617587 = 31617610
47 + 31617563 = 31617610
107 + 31617503 = 31617610
113 + 31617497 = 31617610
149 + 31617461 = 31617610
179 + 31617431 = 31617610
197 + 31617413 = 31617610
239 + 31617371 = 31617610

Showing the first eight; more decompositions exist.
