Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17644, here are decompositions:
- 17 + 17627 = 17644
- 47 + 17597 = 17644
- 71 + 17573 = 17644
- 167 + 17477 = 17644
- 173 + 17471 = 17644
- 227 + 17417 = 17644
- 251 + 17393 = 17644
- 257 + 17387 = 17644
Showing the first eight; more decompositions exist.
