Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16644, here are decompositions:
- 11 + 16633 = 16644
- 13 + 16631 = 16644
- 37 + 16607 = 16644
- 41 + 16603 = 16644
- 71 + 16573 = 16644
- 83 + 16561 = 16644
- 97 + 16547 = 16644
- 151 + 16493 = 16644
Showing the first eight; more decompositions exist.
