Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613196, here are decompositions:

5 + 31613191 = 31613196
53 + 31613143 = 31613196
59 + 31613137 = 31613196
79 + 31613117 = 31613196
89 + 31613107 = 31613196
227 + 31612969 = 31613196
257 + 31612939 = 31613196
283 + 31612913 = 31613196

Showing the first eight; more decompositions exist.
