Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166272, here are decompositions:

13 + 166259 = 166272
53 + 166219 = 166272
83 + 166189 = 166272
89 + 166183 = 166272
103 + 166169 = 166272
173 + 166099 = 166272
191 + 166081 = 166272
229 + 166043 = 166272

Showing the first eight; more decompositions exist.
