Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601514, here are decompositions:

5 + 31601509 = 31601514
41 + 31601473 = 31601514
97 + 31601417 = 31601514
103 + 31601411 = 31601514
107 + 31601407 = 31601514
157 + 31601357 = 31601514
167 + 31601347 = 31601514
173 + 31601341 = 31601514

Showing the first eight; more decompositions exist.
