Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166260, here are decompositions:

13 + 166247 = 166260
23 + 166237 = 166260
41 + 166219 = 166260
53 + 166207 = 166260
71 + 166189 = 166260
103 + 166157 = 166260
109 + 166151 = 166260
113 + 166147 = 166260

Showing the first eight; more decompositions exist.
