Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601332, here are decompositions:

233 + 31601099 = 31601332
281 + 31601051 = 31601332
449 + 31600883 = 31601332
509 + 31600823 = 31601332
599 + 31600733 = 31601332
809 + 31600523 = 31601332
821 + 31600511 = 31601332
839 + 31600493 = 31601332

Showing the first eight; more decompositions exist.
