Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601074, here are decompositions:

23 + 31601051 = 31601074
191 + 31600883 = 31601074
251 + 31600823 = 31601074
257 + 31600817 = 31601074
353 + 31600721 = 31601074
563 + 31600511 = 31601074
653 + 31600421 = 31601074
773 + 31600301 = 31601074

Showing the first eight; more decompositions exist.
