Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613696, here are decompositions:

67 + 31613629 = 31613696
73 + 31613623 = 31613696
157 + 31613539 = 31613696
313 + 31613383 = 31613696
577 + 31613119 = 31613696
643 + 31613053 = 31613696
727 + 31612969 = 31613696
757 + 31612939 = 31613696

Showing the first eight; more decompositions exist.
