Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601486, here are decompositions:

13 + 31601473 = 31601486
79 + 31601407 = 31601486
127 + 31601359 = 31601486
139 + 31601347 = 31601486
223 + 31601263 = 31601486
283 + 31601203 = 31601486
307 + 31601179 = 31601486
349 + 31601137 = 31601486

Showing the first eight; more decompositions exist.
