Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609064, here are decompositions:

31 + 31609033 = 31609064
127 + 31608937 = 31609064
181 + 31608883 = 31609064
211 + 31608853 = 31609064
241 + 31608823 = 31609064
271 + 31608793 = 31609064
307 + 31608757 = 31609064
337 + 31608727 = 31609064

Showing the first eight; more decompositions exist.
