Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613468, here are decompositions:

31 + 31613437 = 31613468
67 + 31613401 = 31613468
127 + 31613341 = 31613468
241 + 31613227 = 31613468
277 + 31613191 = 31613468
331 + 31613137 = 31613468
349 + 31613119 = 31613468
487 + 31612981 = 31613468

Showing the first eight; more decompositions exist.
