Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15448, here are decompositions:
- 5 + 15443 = 15448
- 47 + 15401 = 15448
- 71 + 15377 = 15448
- 89 + 15359 = 15448
- 149 + 15299 = 15448
- 179 + 15269 = 15448
- 311 + 15137 = 15448
- 317 + 15131 = 15448
Showing the first eight; more decompositions exist.
