Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24740, here are decompositions:
- 7 + 24733 = 24740
- 31 + 24709 = 24740
- 43 + 24697 = 24740
- 109 + 24631 = 24740
- 193 + 24547 = 24740
- 223 + 24517 = 24740
- 241 + 24499 = 24740
- 271 + 24469 = 24740
Showing the first eight; more decompositions exist.
