Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660998, here are decompositions:

11 + 8660987 = 8660998
29 + 8660969 = 8660998
89 + 8660909 = 8660998
107 + 8660891 = 8660998
179 + 8660819 = 8660998
251 + 8660747 = 8660998
257 + 8660741 = 8660998
317 + 8660681 = 8660998

Showing the first eight; more decompositions exist.
