Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609494, here are decompositions:

13 + 31609481 = 31609494
31 + 31609463 = 31609494
41 + 31609453 = 31609494
43 + 31609451 = 31609494
101 + 31609393 = 31609494
113 + 31609381 = 31609494
227 + 31609267 = 31609494
263 + 31609231 = 31609494

Showing the first eight; more decompositions exist.
