Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85166, here are decompositions:

7 + 85159 = 85166
19 + 85147 = 85166
73 + 85093 = 85166
79 + 85087 = 85166
139 + 85027 = 85166
157 + 85009 = 85166
199 + 84967 = 85166
307 + 84859 = 85166

Showing the first eight; more decompositions exist.
