Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165408, here are decompositions:

11 + 165397 = 165408
17 + 165391 = 165408
29 + 165379 = 165408
41 + 165367 = 165408
59 + 165349 = 165408
97 + 165311 = 165408
179 + 165229 = 165408
197 + 165211 = 165408

Showing the first eight; more decompositions exist.
