Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165958, here are decompositions:

11 + 165947 = 165958
17 + 165941 = 165958
71 + 165887 = 165958
101 + 165857 = 165958
179 + 165779 = 165958
239 + 165719 = 165958
251 + 165707 = 165958
257 + 165701 = 165958

Showing the first eight; more decompositions exist.
