Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718066, here are decompositions:

23 + 8718043 = 8718066
53 + 8718013 = 8718066
59 + 8718007 = 8718066
67 + 8717999 = 8718066
73 + 8717993 = 8718066
79 + 8717987 = 8718066
103 + 8717963 = 8718066
107 + 8717959 = 8718066

Showing the first eight; more decompositions exist.
