Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16426, here are decompositions:
- 5 + 16421 = 16426
- 107 + 16319 = 16426
- 173 + 16253 = 16426
- 197 + 16229 = 16426
- 233 + 16193 = 16426
- 239 + 16187 = 16426
- 353 + 16073 = 16426
- 359 + 16067 = 16426
Showing the first eight; more decompositions exist.
