Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666154, here are decompositions:

17 + 8666137 = 8666154
61 + 8666093 = 8666154
97 + 8666057 = 8666154
103 + 8666051 = 8666154
127 + 8666027 = 8666154
131 + 8666023 = 8666154
137 + 8666017 = 8666154
163 + 8665991 = 8666154

Showing the first eight; more decompositions exist.
