Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609716, here are decompositions:

13 + 31609703 = 31609716
23 + 31609693 = 31609716
37 + 31609679 = 31609716
107 + 31609609 = 31609716
139 + 31609577 = 31609716
167 + 31609549 = 31609716
197 + 31609519 = 31609716
223 + 31609493 = 31609716

Showing the first eight; more decompositions exist.
