Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16408, here are decompositions:
- 47 + 16361 = 16408
- 59 + 16349 = 16408
- 89 + 16319 = 16408
- 107 + 16301 = 16408
- 179 + 16229 = 16408
- 191 + 16217 = 16408
- 269 + 16139 = 16408
- 281 + 16127 = 16408
Showing the first eight; more decompositions exist.
