Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166266, here are decompositions:

7 + 166259 = 166266
19 + 166247 = 166266
29 + 166237 = 166266
47 + 166219 = 166266
59 + 166207 = 166266
83 + 166183 = 166266
97 + 166169 = 166266
109 + 166157 = 166266

Showing the first eight; more decompositions exist.
