Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718198, here are decompositions:

7 + 8718191 = 8718198
89 + 8718109 = 8718198
101 + 8718097 = 8718198
107 + 8718091 = 8718198
109 + 8718089 = 8718198
191 + 8718007 = 8718198
199 + 8717999 = 8718198
211 + 8717987 = 8718198

Showing the first eight; more decompositions exist.
