Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567356, here are decompositions:

43 + 31567313 = 31567356
59 + 31567297 = 31567356
89 + 31567267 = 31567356
137 + 31567219 = 31567356
199 + 31567157 = 31567356
269 + 31567087 = 31567356
307 + 31567049 = 31567356
313 + 31567043 = 31567356

Showing the first eight; more decompositions exist.
