Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617676, here are decompositions:

3 + 31617673 = 31617676
17 + 31617659 = 31617676
47 + 31617629 = 31617676
89 + 31617587 = 31617676
113 + 31617563 = 31617676
173 + 31617503 = 31617676
179 + 31617497 = 31617676
227 + 31617449 = 31617676

Showing the first eight; more decompositions exist.
