Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613726, here are decompositions:

7 + 31613719 = 31613726
97 + 31613629 = 31613726
103 + 31613623 = 31613726
349 + 31613377 = 31613726
499 + 31613227 = 31613726
607 + 31613119 = 31613726
619 + 31613107 = 31613726
673 + 31613053 = 31613726

Showing the first eight; more decompositions exist.
