Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718122, here are decompositions:

13 + 8718109 = 8718122
19 + 8718103 = 8718122
31 + 8718091 = 8718122
79 + 8718043 = 8718122
109 + 8718013 = 8718122
163 + 8717959 = 8718122
241 + 8717881 = 8718122
313 + 8717809 = 8718122

Showing the first eight; more decompositions exist.
