Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702166, here are decompositions:

7 + 8702159 = 8702166
17 + 8702149 = 8702166
29 + 8702137 = 8702166
59 + 8702107 = 8702166
73 + 8702093 = 8702166
103 + 8702063 = 8702166
157 + 8702009 = 8702166
167 + 8701999 = 8702166

Showing the first eight; more decompositions exist.
