Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617684, here are decompositions:

5 + 31617679 = 31617684
11 + 31617673 = 31617684
17 + 31617667 = 31617684
53 + 31617631 = 31617684
97 + 31617587 = 31617684
101 + 31617583 = 31617684
151 + 31617533 = 31617684
181 + 31617503 = 31617684

Showing the first eight; more decompositions exist.
