Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661126, here are decompositions:

7 + 8661119 = 8661126
37 + 8661089 = 8661126
79 + 8661047 = 8661126
83 + 8661043 = 8661126
139 + 8660987 = 8661126
157 + 8660969 = 8661126
179 + 8660947 = 8661126
193 + 8660933 = 8661126

Showing the first eight; more decompositions exist.
