Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567726, here are decompositions:

17 + 31567709 = 31567726
53 + 31567673 = 31567726
83 + 31567643 = 31567726
89 + 31567637 = 31567726
107 + 31567619 = 31567726
167 + 31567559 = 31567726
173 + 31567553 = 31567726
569 + 31567157 = 31567726

Showing the first eight; more decompositions exist.
