Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566232, here are decompositions:

11 + 31566221 = 31566232
41 + 31566191 = 31566232
101 + 31566131 = 31566232
149 + 31566083 = 31566232
239 + 31565993 = 31566232
251 + 31565981 = 31566232
263 + 31565969 = 31566232
461 + 31565771 = 31566232

Showing the first eight; more decompositions exist.
