Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567244, here are decompositions:

3 + 31567241 = 31567244
13 + 31567231 = 31567244
31 + 31567213 = 31567244
157 + 31567087 = 31567244
271 + 31566973 = 31567244
277 + 31566967 = 31567244
613 + 31566631 = 31567244
727 + 31566517 = 31567244

Showing the first eight; more decompositions exist.
