Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660010, here are decompositions:

11 + 8659999 = 8660010
13 + 8659997 = 8660010
53 + 8659957 = 8660010
61 + 8659949 = 8660010
71 + 8659939 = 8660010
83 + 8659927 = 8660010
89 + 8659921 = 8660010
97 + 8659913 = 8660010

Showing the first eight; more decompositions exist.
