Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631224, here are decompositions:

31 + 8631193 = 8631224
73 + 8631151 = 8631224
127 + 8631097 = 8631224
223 + 8631001 = 8631224
241 + 8630983 = 8631224
367 + 8630857 = 8631224
373 + 8630851 = 8631224
487 + 8630737 = 8631224

Showing the first eight; more decompositions exist.
