Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567308, here are decompositions:

11 + 31567297 = 31567308
29 + 31567279 = 31567308
37 + 31567271 = 31567308
41 + 31567267 = 31567308
67 + 31567241 = 31567308
89 + 31567219 = 31567308
151 + 31567157 = 31567308
389 + 31566919 = 31567308

Showing the first eight; more decompositions exist.
