Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601350, here are decompositions:

3 + 31601347 = 31601350
83 + 31601267 = 31601350
251 + 31601099 = 31601350
467 + 31600883 = 31601350
491 + 31600859 = 31601350
617 + 31600733 = 31601350
647 + 31600703 = 31601350
821 + 31600529 = 31601350

Showing the first eight; more decompositions exist.
