Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165730, here are decompositions:

11 + 165719 = 165730
17 + 165713 = 165730
23 + 165707 = 165730
29 + 165701 = 165730
113 + 165617 = 165730
179 + 165551 = 165730
197 + 165533 = 165730
251 + 165479 = 165730

Showing the first eight; more decompositions exist.
