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.
