Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613756, here are decompositions:

37 + 31613719 = 31613756
127 + 31613629 = 31613756
373 + 31613383 = 31613756
379 + 31613377 = 31613756
613 + 31613143 = 31613756
619 + 31613137 = 31613756
787 + 31612969 = 31613756
883 + 31612873 = 31613756

Showing the first eight; more decompositions exist.
