Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601068, here are decompositions:

17 + 31601051 = 31601068
251 + 31600817 = 31601068
269 + 31600799 = 31601068
347 + 31600721 = 31601068
449 + 31600619 = 31601068
557 + 31600511 = 31601068
617 + 31600451 = 31601068
647 + 31600421 = 31601068

Showing the first eight; more decompositions exist.
