Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601608, here are decompositions:

41 + 31601567 = 31601608
191 + 31601417 = 31601608
197 + 31601411 = 31601608
251 + 31601357 = 31601608
509 + 31601099 = 31601608
557 + 31601051 = 31601608
809 + 31600799 = 31601608
887 + 31600721 = 31601608

Showing the first eight; more decompositions exist.
