Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567666, here are decompositions:

17 + 31567649 = 31567666
23 + 31567643 = 31567666
29 + 31567637 = 31567666
47 + 31567619 = 31567666
107 + 31567559 = 31567666
113 + 31567553 = 31567666
239 + 31567427 = 31567666
269 + 31567397 = 31567666

Showing the first eight; more decompositions exist.
