Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613294, here are decompositions:

3 + 31613291 = 31613294
67 + 31613227 = 31613294
103 + 31613191 = 31613294
151 + 31613143 = 31613294
157 + 31613137 = 31613294
241 + 31613053 = 31613294
313 + 31612981 = 31613294
421 + 31612873 = 31613294

Showing the first eight; more decompositions exist.
