Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567316, here are decompositions:

3 + 31567313 = 31567316
19 + 31567297 = 31567316
37 + 31567279 = 31567316
97 + 31567219 = 31567316
103 + 31567213 = 31567316
163 + 31567153 = 31567316
229 + 31567087 = 31567316
337 + 31566979 = 31567316

Showing the first eight; more decompositions exist.
