Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646960, here are decompositions:

11 + 8646949 = 8646960
13 + 8646947 = 8646960
17 + 8646943 = 8646960
31 + 8646929 = 8646960
61 + 8646899 = 8646960
71 + 8646889 = 8646960
107 + 8646853 = 8646960
109 + 8646851 = 8646960

Showing the first eight; more decompositions exist.
