Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165910, here are decompositions:

23 + 165887 = 165910
53 + 165857 = 165910
131 + 165779 = 165910
191 + 165719 = 165910
197 + 165713 = 165910
257 + 165653 = 165910
293 + 165617 = 165910
359 + 165551 = 165910

Showing the first eight; more decompositions exist.
