Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544224, here are decompositions:

3 + 31544221 = 31544224
11 + 31544213 = 31544224
17 + 31544207 = 31544224
53 + 31544171 = 31544224
71 + 31544153 = 31544224
167 + 31544057 = 31544224
191 + 31544033 = 31544224
227 + 31543997 = 31544224

Showing the first eight; more decompositions exist.
