Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609696, here are decompositions:

3 + 31609693 = 31609696
5 + 31609691 = 31609696
17 + 31609679 = 31609696
113 + 31609583 = 31609696
149 + 31609547 = 31609696
197 + 31609499 = 31609696
227 + 31609469 = 31609696
233 + 31609463 = 31609696

Showing the first eight; more decompositions exist.
