Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65740, here are decompositions:
- 11 + 65729 = 65740
- 23 + 65717 = 65740
- 41 + 65699 = 65740
- 53 + 65687 = 65740
- 83 + 65657 = 65740
- 89 + 65651 = 65740
- 107 + 65633 = 65740
- 131 + 65609 = 65740
Showing the first eight; more decompositions exist.
