Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567314, here are decompositions:

17 + 31567297 = 31567314
43 + 31567271 = 31567314
47 + 31567267 = 31567314
73 + 31567241 = 31567314
83 + 31567231 = 31567314
101 + 31567213 = 31567314
157 + 31567157 = 31567314
223 + 31567091 = 31567314

Showing the first eight; more decompositions exist.
