Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718018, here are decompositions:

5 + 8718013 = 8718018
7 + 8718011 = 8718018
11 + 8718007 = 8718018
19 + 8717999 = 8718018
31 + 8717987 = 8718018
37 + 8717981 = 8718018
59 + 8717959 = 8718018
79 + 8717939 = 8718018

Showing the first eight; more decompositions exist.
