Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661168, here are decompositions:

7 + 8661161 = 8661168
31 + 8661137 = 8661168
79 + 8661089 = 8661168
107 + 8661061 = 8661168
167 + 8661001 = 8661168
181 + 8660987 = 8661168
199 + 8660969 = 8661168
239 + 8660929 = 8661168

Showing the first eight; more decompositions exist.
