Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567494, here are decompositions:

43 + 31567451 = 31567494
67 + 31567427 = 31567494
83 + 31567411 = 31567494
97 + 31567397 = 31567494
181 + 31567313 = 31567494
197 + 31567297 = 31567494
223 + 31567271 = 31567494
227 + 31567267 = 31567494

Showing the first eight; more decompositions exist.
