Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613304, here are decompositions:

13 + 31613291 = 31613304
61 + 31613243 = 31613304
113 + 31613191 = 31613304
167 + 31613137 = 31613304
197 + 31613107 = 31613304
251 + 31613053 = 31613304
277 + 31613027 = 31613304
313 + 31612991 = 31613304

Showing the first eight; more decompositions exist.
