Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16650, here are decompositions:
- 17 + 16633 = 16650
- 19 + 16631 = 16650
- 31 + 16619 = 16650
- 43 + 16607 = 16650
- 47 + 16603 = 16650
- 83 + 16567 = 16650
- 89 + 16561 = 16650
- 97 + 16553 = 16650
Showing the first eight; more decompositions exist.
