Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718180, here are decompositions:

17 + 8718163 = 8718180
67 + 8718113 = 8718180
71 + 8718109 = 8718180
83 + 8718097 = 8718180
89 + 8718091 = 8718180
137 + 8718043 = 8718180
167 + 8718013 = 8718180
173 + 8718007 = 8718180

Showing the first eight; more decompositions exist.
