Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718186, here are decompositions:

23 + 8718163 = 8718186
73 + 8718113 = 8718186
83 + 8718103 = 8718186
89 + 8718097 = 8718186
97 + 8718089 = 8718186
173 + 8718013 = 8718186
179 + 8718007 = 8718186
193 + 8717993 = 8718186

Showing the first eight; more decompositions exist.
