Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165288, here are decompositions:

41 + 165247 = 165288
59 + 165229 = 165288
107 + 165181 = 165288
127 + 165161 = 165288
199 + 165089 = 165288
229 + 165059 = 165288
239 + 165049 = 165288
241 + 165047 = 165288

Showing the first eight; more decompositions exist.
