Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660086, here are decompositions:

5 + 8660081 = 8660086
47 + 8660039 = 8660086
53 + 8660033 = 8660086
89 + 8659997 = 8660086
137 + 8659949 = 8660086
173 + 8659913 = 8660086
293 + 8659793 = 8660086
317 + 8659769 = 8660086

Showing the first eight; more decompositions exist.
