Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617692, here are decompositions:

3 + 31617689 = 31617692
13 + 31617679 = 31617692
19 + 31617673 = 31617692
61 + 31617631 = 31617692
109 + 31617583 = 31617692
163 + 31617529 = 31617692
199 + 31617493 = 31617692
283 + 31617409 = 31617692

Showing the first eight; more decompositions exist.
