Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65724, here are decompositions:

5 + 65719 = 65724
7 + 65717 = 65724
11 + 65713 = 65724
17 + 65707 = 65724
23 + 65701 = 65724
37 + 65687 = 65724
47 + 65677 = 65724
67 + 65657 = 65724

Showing the first eight; more decompositions exist.
