Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601374, here are decompositions:

17 + 31601357 = 31601374
107 + 31601267 = 31601374
491 + 31600883 = 31601374
557 + 31600817 = 31601374
641 + 31600733 = 31601374
653 + 31600721 = 31601374
863 + 31600511 = 31601374
881 + 31600493 = 31601374

Showing the first eight; more decompositions exist.
