Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601460, here are decompositions:

43 + 31601417 = 31601460
53 + 31601407 = 31601460
67 + 31601393 = 31601460
101 + 31601359 = 31601460
103 + 31601357 = 31601460
113 + 31601347 = 31601460
193 + 31601267 = 31601460
197 + 31601263 = 31601460

Showing the first eight; more decompositions exist.
