Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607612, here are decompositions:

13 + 31607599 = 31607612
31 + 31607581 = 31607612
61 + 31607551 = 31607612
109 + 31607503 = 31607612
139 + 31607473 = 31607612
151 + 31607461 = 31607612
163 + 31607449 = 31607612
271 + 31607341 = 31607612

Showing the first eight; more decompositions exist.
