Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165796, here are decompositions:

17 + 165779 = 165796
47 + 165749 = 165796
83 + 165713 = 165796
89 + 165707 = 165796
179 + 165617 = 165796
227 + 165569 = 165796
263 + 165533 = 165796
269 + 165527 = 165796

Showing the first eight; more decompositions exist.
