Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567876, here are decompositions:

17 + 31567859 = 31567876
107 + 31567769 = 31567876
167 + 31567709 = 31567876
227 + 31567649 = 31567876
233 + 31567643 = 31567876
239 + 31567637 = 31567876
257 + 31567619 = 31567876
317 + 31567559 = 31567876

Showing the first eight; more decompositions exist.
