Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718210, here are decompositions:

13 + 8718197 = 8718210
19 + 8718191 = 8718210
47 + 8718163 = 8718210
97 + 8718113 = 8718210
101 + 8718109 = 8718210
107 + 8718103 = 8718210
113 + 8718097 = 8718210
167 + 8718043 = 8718210

Showing the first eight; more decompositions exist.
