Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609460, here are decompositions:

7 + 31609453 = 31609460
67 + 31609393 = 31609460
79 + 31609381 = 31609460
193 + 31609267 = 31609460
229 + 31609231 = 31609460
271 + 31609189 = 31609460
349 + 31609111 = 31609460
367 + 31609093 = 31609460

Showing the first eight; more decompositions exist.
