Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660920, here are decompositions:

11 + 8660909 = 8660920
29 + 8660891 = 8660920
101 + 8660819 = 8660920
167 + 8660753 = 8660920
173 + 8660747 = 8660920
179 + 8660741 = 8660920
197 + 8660723 = 8660920
227 + 8660693 = 8660920

Showing the first eight; more decompositions exist.
