Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166236, here are decompositions:

17 + 166219 = 166236
29 + 166207 = 166236
47 + 166189 = 166236
53 + 166183 = 166236
67 + 166169 = 166236
79 + 166157 = 166236
89 + 166147 = 166236
137 + 166099 = 166236

Showing the first eight; more decompositions exist.
