Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613214, here are decompositions:

23 + 31613191 = 31613214
43 + 31613171 = 31613214
71 + 31613143 = 31613214
97 + 31613117 = 31613214
107 + 31613107 = 31613214
223 + 31612991 = 31613214
233 + 31612981 = 31613214
263 + 31612951 = 31613214

Showing the first eight; more decompositions exist.
