Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567446, here are decompositions:

17 + 31567429 = 31567446
19 + 31567427 = 31567446
149 + 31567297 = 31567446
167 + 31567279 = 31567446
179 + 31567267 = 31567446
227 + 31567219 = 31567446
233 + 31567213 = 31567446
293 + 31567153 = 31567446

Showing the first eight; more decompositions exist.
