Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609996, here are decompositions:

3 + 31609993 = 31609996
23 + 31609973 = 31609996
29 + 31609967 = 31609996
59 + 31609937 = 31609996
113 + 31609883 = 31609996
149 + 31609847 = 31609996
227 + 31609769 = 31609996
293 + 31609703 = 31609996

Showing the first eight; more decompositions exist.
