Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609914, here are decompositions:

31 + 31609883 = 31609914
43 + 31609871 = 31609914
53 + 31609861 = 31609914
67 + 31609847 = 31609914
101 + 31609813 = 31609914
137 + 31609777 = 31609914
173 + 31609741 = 31609914
191 + 31609723 = 31609914

Showing the first eight; more decompositions exist.
