Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609954, here are decompositions:

17 + 31609937 = 31609954
23 + 31609931 = 31609954
71 + 31609883 = 31609954
83 + 31609871 = 31609954
107 + 31609847 = 31609954
251 + 31609703 = 31609954
263 + 31609691 = 31609954
293 + 31609661 = 31609954

Showing the first eight; more decompositions exist.
