Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613108, here are decompositions:

127 + 31612981 = 31613108
139 + 31612969 = 31613108
157 + 31612951 = 31613108
277 + 31612831 = 31613108
349 + 31612759 = 31613108
379 + 31612729 = 31613108
487 + 31612621 = 31613108
577 + 31612531 = 31613108

Showing the first eight; more decompositions exist.
