Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609694, here are decompositions:

3 + 31609691 = 31609694
163 + 31609531 = 31609694
241 + 31609453 = 31609694
313 + 31609381 = 31609694
463 + 31609231 = 31609694
577 + 31609117 = 31609694
601 + 31609093 = 31609694
607 + 31609087 = 31609694

Showing the first eight; more decompositions exist.
