Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609774, here are decompositions:

5 + 31609769 = 31609774
71 + 31609703 = 31609774
83 + 31609691 = 31609774
113 + 31609661 = 31609774
191 + 31609583 = 31609774
197 + 31609577 = 31609774
227 + 31609547 = 31609774
233 + 31609541 = 31609774

Showing the first eight; more decompositions exist.
