Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166182, here are decompositions:

13 + 166169 = 166182
31 + 166151 = 166182
83 + 166099 = 166182
101 + 166081 = 166182
139 + 166043 = 166182
151 + 166031 = 166182
199 + 165983 = 166182
241 + 165941 = 166182

Showing the first eight; more decompositions exist.
