Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660844, here are decompositions:

47 + 8660797 = 8660844
97 + 8660747 = 8660844
103 + 8660741 = 8660844
151 + 8660693 = 8660844
163 + 8660681 = 8660844
173 + 8660671 = 8660844
191 + 8660653 = 8660844
233 + 8660611 = 8660844

Showing the first eight; more decompositions exist.
