Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566712, here are decompositions:

3 + 31566709 = 31566712
53 + 31566659 = 31566712
101 + 31566611 = 31566712
113 + 31566599 = 31566712
239 + 31566473 = 31566712
263 + 31566449 = 31566712
269 + 31566443 = 31566712
383 + 31566329 = 31566712

Showing the first eight; more decompositions exist.
