Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607458, here are decompositions:

11 + 31607447 = 31607458
59 + 31607399 = 31607458
101 + 31607357 = 31607458
131 + 31607327 = 31607458
149 + 31607309 = 31607458
167 + 31607291 = 31607458
251 + 31607207 = 31607458
257 + 31607201 = 31607458

Showing the first eight; more decompositions exist.
