Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566226, here are decompositions:

5 + 31566221 = 31566226
59 + 31566167 = 31566226
89 + 31566137 = 31566226
149 + 31566077 = 31566226
233 + 31565993 = 31566226
257 + 31565969 = 31566226
563 + 31565663 = 31566226
827 + 31565399 = 31566226

Showing the first eight; more decompositions exist.
