Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567338, here are decompositions:

41 + 31567297 = 31567338
59 + 31567279 = 31567338
67 + 31567271 = 31567338
71 + 31567267 = 31567338
97 + 31567241 = 31567338
107 + 31567231 = 31567338
181 + 31567157 = 31567338
251 + 31567087 = 31567338

Showing the first eight; more decompositions exist.
