Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609482, here are decompositions:

13 + 31609469 = 31609482
19 + 31609463 = 31609482
29 + 31609453 = 31609482
31 + 31609451 = 31609482
89 + 31609393 = 31609482
101 + 31609381 = 31609482
193 + 31609289 = 31609482
251 + 31609231 = 31609482

Showing the first eight; more decompositions exist.
