Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661108, here are decompositions:

19 + 8661089 = 8661108
47 + 8661061 = 8661108
59 + 8661049 = 8661108
61 + 8661047 = 8661108
107 + 8661001 = 8661108
139 + 8660969 = 8661108
179 + 8660929 = 8661108
199 + 8660909 = 8661108

Showing the first eight; more decompositions exist.
