Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569294, here are decompositions:

7 + 31569287 = 31569294
13 + 31569281 = 31569294
17 + 31569277 = 31569294
37 + 31569257 = 31569294
47 + 31569247 = 31569294
61 + 31569233 = 31569294
101 + 31569193 = 31569294
137 + 31569157 = 31569294

Showing the first eight; more decompositions exist.
