Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617764, here are decompositions:

7 + 31617757 = 31617764
67 + 31617697 = 31617764
97 + 31617667 = 31617764
181 + 31617583 = 31617764
271 + 31617493 = 31617764
307 + 31617457 = 31617764
631 + 31617133 = 31617764
691 + 31617073 = 31617764

Showing the first eight; more decompositions exist.
