Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718224, here are decompositions:

3 + 8718221 = 8718224
7 + 8718217 = 8718224
61 + 8718163 = 8718224
127 + 8718097 = 8718224
181 + 8718043 = 8718224
211 + 8718013 = 8718224
367 + 8717857 = 8718224
421 + 8717803 = 8718224

Showing the first eight; more decompositions exist.
