Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82740, here are decompositions:
- 11 + 82729 = 82740
- 13 + 82727 = 82740
- 17 + 82723 = 82740
- 19 + 82721 = 82740
- 41 + 82699 = 82740
- 83 + 82657 = 82740
- 89 + 82651 = 82740
- 107 + 82633 = 82740
Showing the first eight; more decompositions exist.
