Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613222, here are decompositions:

31 + 31613191 = 31613222
79 + 31613143 = 31613222
103 + 31613119 = 31613222
241 + 31612981 = 31613222
271 + 31612951 = 31613222
283 + 31612939 = 31613222
331 + 31612891 = 31613222
349 + 31612873 = 31613222

Showing the first eight; more decompositions exist.
