Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660016, here are decompositions:

17 + 8659999 = 8660016
19 + 8659997 = 8660016
59 + 8659957 = 8660016
67 + 8659949 = 8660016
89 + 8659927 = 8660016
103 + 8659913 = 8660016
107 + 8659909 = 8660016
149 + 8659867 = 8660016

Showing the first eight; more decompositions exist.
