Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601188, here are decompositions:

89 + 31601099 = 31601188
137 + 31601051 = 31601188
389 + 31600799 = 31601188
467 + 31600721 = 31601188
569 + 31600619 = 31601188
659 + 31600529 = 31601188
677 + 31600511 = 31601188
881 + 31600307 = 31601188

Showing the first eight; more decompositions exist.
