Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613350, here are decompositions:

17 + 31613333 = 31613350
59 + 31613291 = 31613350
101 + 31613249 = 31613350
107 + 31613243 = 31613350
179 + 31613171 = 31613350
233 + 31613117 = 31613350
359 + 31612991 = 31613350
389 + 31612961 = 31613350

Showing the first eight; more decompositions exist.
