Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666166, here are decompositions:

7 + 8666159 = 8666166
13 + 8666153 = 8666166
29 + 8666137 = 8666166
73 + 8666093 = 8666166
97 + 8666069 = 8666166
107 + 8666059 = 8666166
109 + 8666057 = 8666166
139 + 8666027 = 8666166

Showing the first eight; more decompositions exist.
