Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15502, here are decompositions:
- 5 + 15497 = 15502
- 29 + 15473 = 15502
- 41 + 15461 = 15502
- 59 + 15443 = 15502
- 89 + 15413 = 15502
- 101 + 15401 = 15502
- 173 + 15329 = 15502
- 233 + 15269 = 15502
Showing the first eight; more decompositions exist.
