Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17816, here are decompositions:
- 67 + 17749 = 17816
- 79 + 17737 = 17816
- 103 + 17713 = 17816
- 109 + 17707 = 17816
- 157 + 17659 = 17816
- 193 + 17623 = 17816
- 277 + 17539 = 17816
- 307 + 17509 = 17816
Showing the first eight; more decompositions exist.
