Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613168, here are decompositions:

31 + 31613137 = 31613168
61 + 31613107 = 31613168
199 + 31612969 = 31613168
229 + 31612939 = 31613168
277 + 31612891 = 31613168
337 + 31612831 = 31613168
409 + 31612759 = 31613168
421 + 31612747 = 31613168

Showing the first eight; more decompositions exist.
