Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566224, here are decompositions:

3 + 31566221 = 31566224
73 + 31566151 = 31566224
163 + 31566061 = 31566224
181 + 31566043 = 31566224
211 + 31566013 = 31566224
223 + 31566001 = 31566224
271 + 31565953 = 31566224
307 + 31565917 = 31566224

Showing the first eight; more decompositions exist.
