Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718918, here are decompositions:

11 + 8718907 = 8718918
31 + 8718887 = 8718918
37 + 8718881 = 8718918
41 + 8718877 = 8718918
59 + 8718859 = 8718918
67 + 8718851 = 8718918
79 + 8718839 = 8718918
107 + 8718811 = 8718918

Showing the first eight; more decompositions exist.
