Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661950, here are decompositions:

7 + 8661943 = 8661950
61 + 8661889 = 8661950
67 + 8661883 = 8661950
79 + 8661871 = 8661950
109 + 8661841 = 8661950
151 + 8661799 = 8661950
181 + 8661769 = 8661950
223 + 8661727 = 8661950

Showing the first eight; more decompositions exist.
