Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567310, here are decompositions:

13 + 31567297 = 31567310
31 + 31567279 = 31567310
43 + 31567267 = 31567310
79 + 31567231 = 31567310
97 + 31567213 = 31567310
157 + 31567153 = 31567310
223 + 31567087 = 31567310
331 + 31566979 = 31567310

Showing the first eight; more decompositions exist.
