Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607254, here are decompositions:

17 + 31607237 = 31607254
47 + 31607207 = 31607254
53 + 31607201 = 31607254
101 + 31607153 = 31607254
167 + 31607087 = 31607254
257 + 31606997 = 31607254
281 + 31606973 = 31607254
311 + 31606943 = 31607254

Showing the first eight; more decompositions exist.
