Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617794, here are decompositions:

31 + 31617763 = 31617794
37 + 31617757 = 31617794
97 + 31617697 = 31617794
127 + 31617667 = 31617794
163 + 31617631 = 31617794
211 + 31617583 = 31617794
337 + 31617457 = 31617794
421 + 31617373 = 31617794

Showing the first eight; more decompositions exist.
