Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601912, here are decompositions:

31 + 31601881 = 31601912
103 + 31601809 = 31601912
241 + 31601671 = 31601912
283 + 31601629 = 31601912
373 + 31601539 = 31601912
439 + 31601473 = 31601912
571 + 31601341 = 31601912
709 + 31601203 = 31601912

Showing the first eight; more decompositions exist.
