Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613744, here are decompositions:

163 + 31613581 = 31613744
193 + 31613551 = 31613744
307 + 31613437 = 31613744
367 + 31613377 = 31613744
601 + 31613143 = 31613744
607 + 31613137 = 31613744
691 + 31613053 = 31613744
853 + 31612891 = 31613744

Showing the first eight; more decompositions exist.
