Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613198, here are decompositions:

7 + 31613191 = 31613198
61 + 31613137 = 31613198
79 + 31613119 = 31613198
229 + 31612969 = 31613198
307 + 31612891 = 31613198
367 + 31612831 = 31613198
439 + 31612759 = 31613198
571 + 31612627 = 31613198

Showing the first eight; more decompositions exist.
