Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705166, here are decompositions:

7 + 8705159 = 8705166
17 + 8705149 = 8705166
73 + 8705093 = 8705166
79 + 8705087 = 8705166
89 + 8705077 = 8705166
97 + 8705069 = 8705166
109 + 8705057 = 8705166
137 + 8705029 = 8705166

Showing the first eight; more decompositions exist.
