Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617806, here are decompositions:

43 + 31617763 = 31617806
109 + 31617697 = 31617806
127 + 31617679 = 31617806
139 + 31617667 = 31617806
223 + 31617583 = 31617806
277 + 31617529 = 31617806
313 + 31617493 = 31617806
349 + 31617457 = 31617806

Showing the first eight; more decompositions exist.
