Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16772, here are decompositions:
- 13 + 16759 = 16772
- 31 + 16741 = 16772
- 43 + 16729 = 16772
- 73 + 16699 = 16772
- 79 + 16693 = 16772
- 139 + 16633 = 16772
- 199 + 16573 = 16772
- 211 + 16561 = 16772
Showing the first eight; more decompositions exist.
