Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613966, here are decompositions:

3 + 31613963 = 31613966
127 + 31613839 = 31613966
337 + 31613629 = 31613966
739 + 31613227 = 31613966
823 + 31613143 = 31613966
829 + 31613137 = 31613966
859 + 31613107 = 31613966
997 + 31612969 = 31613966

Showing the first eight; more decompositions exist.
