Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609966, here are decompositions:

29 + 31609937 = 31609966
83 + 31609883 = 31609966
173 + 31609793 = 31609966
197 + 31609769 = 31609966
263 + 31609703 = 31609966
383 + 31609583 = 31609966
389 + 31609577 = 31609966
419 + 31609547 = 31609966

Showing the first eight; more decompositions exist.
