Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567548, here are decompositions:

37 + 31567511 = 31567548
97 + 31567451 = 31567548
137 + 31567411 = 31567548
151 + 31567397 = 31567548
179 + 31567369 = 31567548
251 + 31567297 = 31567548
269 + 31567279 = 31567548
277 + 31567271 = 31567548

Showing the first eight; more decompositions exist.
