Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86166, here are decompositions:

5 + 86161 = 86166
23 + 86143 = 86166
29 + 86137 = 86166
53 + 86113 = 86166
83 + 86083 = 86166
89 + 86077 = 86166
97 + 86069 = 86166
137 + 86029 = 86166

Showing the first eight; more decompositions exist.
