Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609466, here are decompositions:

3 + 31609463 = 31609466
13 + 31609453 = 31609466
73 + 31609393 = 31609466
127 + 31609339 = 31609466
199 + 31609267 = 31609466
277 + 31609189 = 31609466
349 + 31609117 = 31609466
373 + 31609093 = 31609466

Showing the first eight; more decompositions exist.
