Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65730, here are decompositions:

11 + 65719 = 65730
13 + 65717 = 65730
17 + 65713 = 65730
23 + 65707 = 65730
29 + 65701 = 65730
31 + 65699 = 65730
43 + 65687 = 65730
53 + 65677 = 65730

Showing the first eight; more decompositions exist.
