Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182166, here are decompositions:

7 + 182159 = 182166
37 + 182129 = 182166
43 + 182123 = 182166
59 + 182107 = 182166
67 + 182099 = 182166
107 + 182059 = 182166
109 + 182057 = 182166
137 + 182029 = 182166

Showing the first eight; more decompositions exist.
