Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718216, here are decompositions:

19 + 8718197 = 8718216
53 + 8718163 = 8718216
103 + 8718113 = 8718216
107 + 8718109 = 8718216
113 + 8718103 = 8718216
127 + 8718089 = 8718216
173 + 8718043 = 8718216
223 + 8717993 = 8718216

Showing the first eight; more decompositions exist.
