Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567696, here are decompositions:

3 + 31567693 = 31567696
23 + 31567673 = 31567696
47 + 31567649 = 31567696
53 + 31567643 = 31567696
59 + 31567637 = 31567696
137 + 31567559 = 31567696
269 + 31567427 = 31567696
383 + 31567313 = 31567696

Showing the first eight; more decompositions exist.
