Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660916, here are decompositions:

7 + 8660909 = 8660916
29 + 8660887 = 8660916
53 + 8660863 = 8660916
97 + 8660819 = 8660916
149 + 8660767 = 8660916
163 + 8660753 = 8660916
193 + 8660723 = 8660916
223 + 8660693 = 8660916

Showing the first eight; more decompositions exist.
