Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8816, here are decompositions:
- 13 + 8803 = 8816
- 37 + 8779 = 8816
- 79 + 8737 = 8816
- 97 + 8719 = 8816
- 103 + 8713 = 8816
- 109 + 8707 = 8816
- 127 + 8689 = 8816
- 139 + 8677 = 8816
Showing the first eight; more decompositions exist.
