Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661012, here are decompositions:

11 + 8661001 = 8661012
29 + 8660983 = 8661012
43 + 8660969 = 8661012
79 + 8660933 = 8661012
83 + 8660929 = 8661012
103 + 8660909 = 8661012
149 + 8660863 = 8661012
193 + 8660819 = 8661012

Showing the first eight; more decompositions exist.
