Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613366, here are decompositions:

139 + 31613227 = 31613366
223 + 31613143 = 31613366
229 + 31613137 = 31613366
313 + 31613053 = 31613366
397 + 31612969 = 31613366
607 + 31612759 = 31613366
613 + 31612753 = 31613366
619 + 31612747 = 31613366

Showing the first eight; more decompositions exist.
