Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166086, here are decompositions:

5 + 166081 = 166086
23 + 166063 = 166086
43 + 166043 = 166086
59 + 166027 = 166086
73 + 166013 = 166086
103 + 165983 = 166086
139 + 165947 = 166086
199 + 165887 = 166086

Showing the first eight; more decompositions exist.
