Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16916, here are decompositions:
- 13 + 16903 = 16916
- 37 + 16879 = 16916
- 73 + 16843 = 16916
- 157 + 16759 = 16916
- 223 + 16693 = 16916
- 283 + 16633 = 16916
- 313 + 16603 = 16916
- 349 + 16567 = 16916
Showing the first eight; more decompositions exist.
