Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567482, here are decompositions:

31 + 31567451 = 31567482
53 + 31567429 = 31567482
71 + 31567411 = 31567482
113 + 31567369 = 31567482
211 + 31567271 = 31567482
241 + 31567241 = 31567482
251 + 31567231 = 31567482
263 + 31567219 = 31567482

Showing the first eight; more decompositions exist.
