Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617964, here are decompositions:

3 + 31617961 = 31617964
5 + 31617959 = 31617964
11 + 31617953 = 31617964
23 + 31617941 = 31617964
101 + 31617863 = 31617964
137 + 31617827 = 31617964
167 + 31617797 = 31617964
251 + 31617713 = 31617964

Showing the first eight; more decompositions exist.
