Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12166, here are decompositions:

3 + 12163 = 12166
5 + 12161 = 12166
17 + 12149 = 12166
23 + 12143 = 12166
47 + 12119 = 12166
53 + 12113 = 12166
59 + 12107 = 12166
179 + 11987 = 12166

Showing the first eight; more decompositions exist.
