Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24420, here are decompositions:
- 7 + 24413 = 24420
- 13 + 24407 = 24420
- 29 + 24391 = 24420
- 41 + 24379 = 24420
- 47 + 24373 = 24420
- 61 + 24359 = 24420
- 83 + 24337 = 24420
- 103 + 24317 = 24420
Showing the first eight; more decompositions exist.
