Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15508, here are decompositions:
- 11 + 15497 = 15508
- 41 + 15467 = 15508
- 47 + 15461 = 15508
- 107 + 15401 = 15508
- 131 + 15377 = 15508
- 149 + 15359 = 15508
- 179 + 15329 = 15508
- 239 + 15269 = 15508
Showing the first eight; more decompositions exist.
