Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613264, here are decompositions:

37 + 31613227 = 31613264
73 + 31613191 = 31613264
127 + 31613137 = 31613264
157 + 31613107 = 31613264
211 + 31613053 = 31613264
283 + 31612981 = 31613264
313 + 31612951 = 31613264
373 + 31612891 = 31613264

Showing the first eight; more decompositions exist.
