Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566256, here are decompositions:

5 + 31566251 = 31566256
89 + 31566167 = 31566256
173 + 31566083 = 31566256
179 + 31566077 = 31566256
263 + 31565993 = 31566256
563 + 31565693 = 31566256
593 + 31565663 = 31566256
653 + 31565603 = 31566256

Showing the first eight; more decompositions exist.
