Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660018, here are decompositions:

19 + 8659999 = 8660018
61 + 8659957 = 8660018
79 + 8659939 = 8660018
97 + 8659921 = 8660018
109 + 8659909 = 8660018
151 + 8659867 = 8660018
181 + 8659837 = 8660018
271 + 8659747 = 8660018

Showing the first eight; more decompositions exist.
