Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567468, here are decompositions:

17 + 31567451 = 31567468
41 + 31567427 = 31567468
71 + 31567397 = 31567468
197 + 31567271 = 31567468
227 + 31567241 = 31567468
311 + 31567157 = 31567468
419 + 31567049 = 31567468
557 + 31566911 = 31567468

Showing the first eight; more decompositions exist.
