Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24780, here are decompositions:
- 13 + 24767 = 24780
- 17 + 24763 = 24780
- 31 + 24749 = 24780
- 47 + 24733 = 24780
- 71 + 24709 = 24780
- 83 + 24697 = 24780
- 89 + 24691 = 24780
- 97 + 24683 = 24780
Showing the first eight; more decompositions exist.
