Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567326, here are decompositions:

13 + 31567313 = 31567326
29 + 31567297 = 31567326
47 + 31567279 = 31567326
59 + 31567267 = 31567326
107 + 31567219 = 31567326
113 + 31567213 = 31567326
173 + 31567153 = 31567326
239 + 31567087 = 31567326

Showing the first eight; more decompositions exist.
