Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567386, here are decompositions:

17 + 31567369 = 31567386
73 + 31567313 = 31567386
89 + 31567297 = 31567386
107 + 31567279 = 31567386
167 + 31567219 = 31567386
173 + 31567213 = 31567386
229 + 31567157 = 31567386
233 + 31567153 = 31567386

Showing the first eight; more decompositions exist.
