Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566244, here are decompositions:

23 + 31566221 = 31566244
53 + 31566191 = 31566244
107 + 31566137 = 31566244
113 + 31566131 = 31566244
167 + 31566077 = 31566244
251 + 31565993 = 31566244
263 + 31565981 = 31566244
641 + 31565603 = 31566244

Showing the first eight; more decompositions exist.
