Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165266, here are decompositions:

19 + 165247 = 165266
37 + 165229 = 165266
163 + 165103 = 165266
229 + 165037 = 165266
313 + 164953 = 165266
373 + 164893 = 165266
457 + 164809 = 165266
499 + 164767 = 165266

Showing the first eight; more decompositions exist.
