Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661080, here are decompositions:

19 + 8661061 = 8661080
31 + 8661049 = 8661080
37 + 8661043 = 8661080
79 + 8661001 = 8661080
97 + 8660983 = 8661080
151 + 8660929 = 8661080
193 + 8660887 = 8661080
283 + 8660797 = 8661080

Showing the first eight; more decompositions exist.
