Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15472, here are decompositions:
- 5 + 15467 = 15472
- 11 + 15461 = 15472
- 29 + 15443 = 15472
- 59 + 15413 = 15472
- 71 + 15401 = 15472
- 89 + 15383 = 15472
- 113 + 15359 = 15472
- 173 + 15299 = 15472
Showing the first eight; more decompositions exist.
