Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661224, here are decompositions:

7 + 8661217 = 8661224
31 + 8661193 = 8661224
43 + 8661181 = 8661224
163 + 8661061 = 8661224
181 + 8661043 = 8661224
223 + 8661001 = 8661224
241 + 8660983 = 8661224
277 + 8660947 = 8661224

Showing the first eight; more decompositions exist.
