Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15412, here are decompositions:
- 11 + 15401 = 15412
- 29 + 15383 = 15412
- 53 + 15359 = 15412
- 83 + 15329 = 15412
- 113 + 15299 = 15412
- 149 + 15263 = 15412
- 179 + 15233 = 15412
- 239 + 15173 = 15412
Showing the first eight; more decompositions exist.
