Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165766, here are decompositions:

17 + 165749 = 165766
47 + 165719 = 165766
53 + 165713 = 165766
59 + 165707 = 165766
113 + 165653 = 165766
149 + 165617 = 165766
179 + 165587 = 165766
197 + 165569 = 165766

Showing the first eight; more decompositions exist.
