Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601032, here are decompositions:

149 + 31600883 = 31601032
173 + 31600859 = 31601032
233 + 31600799 = 31601032
311 + 31600721 = 31601032
503 + 31600529 = 31601032
509 + 31600523 = 31601032
521 + 31600511 = 31601032
773 + 31600259 = 31601032

Showing the first eight; more decompositions exist.
