Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24540, here are decompositions:
- 7 + 24533 = 24540
- 13 + 24527 = 24540
- 23 + 24517 = 24540
- 31 + 24509 = 24540
- 41 + 24499 = 24540
- 59 + 24481 = 24540
- 67 + 24473 = 24540
- 71 + 24469 = 24540
Showing the first eight; more decompositions exist.
