Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609394, here are decompositions:

13 + 31609381 = 31609394
127 + 31609267 = 31609394
163 + 31609231 = 31609394
181 + 31609213 = 31609394
277 + 31609117 = 31609394
283 + 31609111 = 31609394
307 + 31609087 = 31609394
457 + 31608937 = 31609394

Showing the first eight; more decompositions exist.
