Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718206, here are decompositions:

43 + 8718163 = 8718206
97 + 8718109 = 8718206
103 + 8718103 = 8718206
109 + 8718097 = 8718206
163 + 8718043 = 8718206
193 + 8718013 = 8718206
199 + 8718007 = 8718206
337 + 8717869 = 8718206

Showing the first eight; more decompositions exist.
