Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613308, here are decompositions:

17 + 31613291 = 31613308
59 + 31613249 = 31613308
137 + 31613171 = 31613308
191 + 31613117 = 31613308
281 + 31613027 = 31613308
317 + 31612991 = 31613308
347 + 31612961 = 31613308
569 + 31612739 = 31613308

Showing the first eight; more decompositions exist.
