Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24520, here are decompositions:
- 3 + 24517 = 24520
- 11 + 24509 = 24520
- 47 + 24473 = 24520
- 101 + 24419 = 24520
- 107 + 24413 = 24520
- 113 + 24407 = 24520
- 149 + 24371 = 24520
- 191 + 24329 = 24520
Showing the first eight; more decompositions exist.
