Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607350, here are decompositions:

23 + 31607327 = 31607350
41 + 31607309 = 31607350
53 + 31607297 = 31607350
59 + 31607291 = 31607350
113 + 31607237 = 31607350
149 + 31607201 = 31607350
197 + 31607153 = 31607350
263 + 31607087 = 31607350

Showing the first eight; more decompositions exist.
