Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16672, here are decompositions:
- 11 + 16661 = 16672
- 23 + 16649 = 16672
- 41 + 16631 = 16672
- 53 + 16619 = 16672
- 179 + 16493 = 16672
- 191 + 16481 = 16672
- 239 + 16433 = 16672
- 251 + 16421 = 16672
Showing the first eight; more decompositions exist.
