Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567448, here are decompositions:

19 + 31567429 = 31567448
37 + 31567411 = 31567448
79 + 31567369 = 31567448
151 + 31567297 = 31567448
181 + 31567267 = 31567448
229 + 31567219 = 31567448
547 + 31566901 = 31567448
631 + 31566817 = 31567448

Showing the first eight; more decompositions exist.
