Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718126, here are decompositions:

13 + 8718113 = 8718126
17 + 8718109 = 8718126
23 + 8718103 = 8718126
29 + 8718097 = 8718126
37 + 8718089 = 8718126
83 + 8718043 = 8718126
113 + 8718013 = 8718126
127 + 8717999 = 8718126

Showing the first eight; more decompositions exist.
