Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601756, here are decompositions:

13 + 31601743 = 31601756
127 + 31601629 = 31601756
229 + 31601527 = 31601756
283 + 31601473 = 31601756
349 + 31601407 = 31601756
397 + 31601359 = 31601756
409 + 31601347 = 31601756
577 + 31601179 = 31601756

Showing the first eight; more decompositions exist.
