Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533224, here are decompositions:

97 + 31533127 = 31533224
127 + 31533097 = 31533224
211 + 31533013 = 31533224
223 + 31533001 = 31533224
487 + 31532737 = 31533224
571 + 31532653 = 31533224
631 + 31532593 = 31533224
643 + 31532581 = 31533224

Showing the first eight; more decompositions exist.
