Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15424, here are decompositions:
- 11 + 15413 = 15424
- 23 + 15401 = 15424
- 41 + 15383 = 15424
- 47 + 15377 = 15424
- 137 + 15287 = 15424
- 191 + 15233 = 15424
- 197 + 15227 = 15424
- 251 + 15173 = 15424
Showing the first eight; more decompositions exist.
