Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567464, here are decompositions:

13 + 31567451 = 31567464
37 + 31567427 = 31567464
53 + 31567411 = 31567464
67 + 31567397 = 31567464
151 + 31567313 = 31567464
167 + 31567297 = 31567464
193 + 31567271 = 31567464
197 + 31567267 = 31567464

Showing the first eight; more decompositions exist.
