Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13516, here are decompositions:
- 3 + 13513 = 13516
- 17 + 13499 = 13516
- 29 + 13487 = 13516
- 47 + 13469 = 13516
- 53 + 13463 = 13516
- 59 + 13457 = 13516
- 149 + 13367 = 13516
- 179 + 13337 = 13516
Showing the first eight; more decompositions exist.
