Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607358, here are decompositions:

17 + 31607341 = 31607358
31 + 31607327 = 31607358
59 + 31607299 = 31607358
61 + 31607297 = 31607358
67 + 31607291 = 31607358
131 + 31607227 = 31607358
151 + 31607207 = 31607358
157 + 31607201 = 31607358

Showing the first eight; more decompositions exist.
