Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10816, here are decompositions:
- 17 + 10799 = 10816
- 83 + 10733 = 10816
- 107 + 10709 = 10816
- 149 + 10667 = 10816
- 227 + 10589 = 10816
- 257 + 10559 = 10816
- 317 + 10499 = 10816
- 353 + 10463 = 10816
Showing the first eight; more decompositions exist.
