Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524224, here are decompositions:

31 + 31524193 = 31524224
181 + 31524043 = 31524224
211 + 31524013 = 31524224
271 + 31523953 = 31524224
283 + 31523941 = 31524224
307 + 31523917 = 31524224
373 + 31523851 = 31524224
421 + 31523803 = 31524224

Showing the first eight; more decompositions exist.
