Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609644, here are decompositions:

13 + 31609631 = 31609644
61 + 31609583 = 31609644
67 + 31609577 = 31609644
83 + 31609561 = 31609644
97 + 31609547 = 31609644
103 + 31609541 = 31609644
113 + 31609531 = 31609644
151 + 31609493 = 31609644

Showing the first eight; more decompositions exist.
