Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567624, here are decompositions:

3 + 31567621 = 31567624
5 + 31567619 = 31567624
71 + 31567553 = 31567624
113 + 31567511 = 31567624
173 + 31567451 = 31567624
197 + 31567427 = 31567624
227 + 31567397 = 31567624
311 + 31567313 = 31567624

Showing the first eight; more decompositions exist.
