Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661144, here are decompositions:

7 + 8661137 = 8661144
83 + 8661061 = 8661144
97 + 8661047 = 8661144
101 + 8661043 = 8661144
157 + 8660987 = 8661144
197 + 8660947 = 8661144
211 + 8660933 = 8661144
223 + 8660921 = 8661144

Showing the first eight; more decompositions exist.
