Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613174, here are decompositions:

3 + 31613171 = 31613174
31 + 31613143 = 31613174
37 + 31613137 = 31613174
67 + 31613107 = 31613174
193 + 31612981 = 31613174
223 + 31612951 = 31613174
283 + 31612891 = 31613174
421 + 31612753 = 31613174

Showing the first eight; more decompositions exist.
