Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613066, here are decompositions:

13 + 31613053 = 31613066
97 + 31612969 = 31613066
127 + 31612939 = 31613066
193 + 31612873 = 31613066
307 + 31612759 = 31613066
313 + 31612753 = 31613066
337 + 31612729 = 31613066
439 + 31612627 = 31613066

Showing the first eight; more decompositions exist.
