Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15418, here are decompositions:
- 5 + 15413 = 15418
- 17 + 15401 = 15418
- 41 + 15377 = 15418
- 59 + 15359 = 15418
- 89 + 15329 = 15418
- 131 + 15287 = 15418
- 149 + 15269 = 15418
- 191 + 15227 = 15418
Showing the first eight; more decompositions exist.
