Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165392, here are decompositions:

13 + 165379 = 165392
43 + 165349 = 165392
61 + 165331 = 165392
79 + 165313 = 165392
163 + 165229 = 165392
181 + 165211 = 165392
211 + 165181 = 165392
313 + 165079 = 165392

Showing the first eight; more decompositions exist.
