Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601056, here are decompositions:

5 + 31601051 = 31601056
173 + 31600883 = 31601056
197 + 31600859 = 31601056
233 + 31600823 = 31601056
239 + 31600817 = 31601056
257 + 31600799 = 31601056
353 + 31600703 = 31601056
563 + 31600493 = 31601056

Showing the first eight; more decompositions exist.
