Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16516, here are decompositions:
- 23 + 16493 = 16516
- 29 + 16487 = 16516
- 83 + 16433 = 16516
- 89 + 16427 = 16516
- 167 + 16349 = 16516
- 197 + 16319 = 16516
- 263 + 16253 = 16516
- 293 + 16223 = 16516
Showing the first eight; more decompositions exist.
