Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617626, here are decompositions:

43 + 31617583 = 31617626
67 + 31617559 = 31617626
97 + 31617529 = 31617626
223 + 31617403 = 31617626
373 + 31617253 = 31617626
577 + 31617049 = 31617626
613 + 31617013 = 31617626
709 + 31616917 = 31617626

Showing the first eight; more decompositions exist.
