Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601086, here are decompositions:

3 + 31601083 = 31601086
227 + 31600859 = 31601086
263 + 31600823 = 31601086
269 + 31600817 = 31601086
353 + 31600733 = 31601086
383 + 31600703 = 31601086
467 + 31600619 = 31601086
557 + 31600529 = 31601086

Showing the first eight; more decompositions exist.
