Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24864, here are decompositions:
- 5 + 24859 = 24864
- 13 + 24851 = 24864
- 17 + 24847 = 24864
- 23 + 24841 = 24864
- 43 + 24821 = 24864
- 71 + 24793 = 24864
- 83 + 24781 = 24864
- 97 + 24767 = 24864
Showing the first eight; more decompositions exist.
