Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567678, here are decompositions:

5 + 31567673 = 31567678
29 + 31567649 = 31567678
41 + 31567637 = 31567678
59 + 31567619 = 31567678
167 + 31567511 = 31567678
227 + 31567451 = 31567678
251 + 31567427 = 31567678
281 + 31567397 = 31567678

Showing the first eight; more decompositions exist.
