Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24720, here are decompositions:
- 11 + 24709 = 24720
- 23 + 24697 = 24720
- 29 + 24691 = 24720
- 37 + 24683 = 24720
- 43 + 24677 = 24720
- 61 + 24659 = 24720
- 89 + 24631 = 24720
- 97 + 24623 = 24720
Showing the first eight; more decompositions exist.
