Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4816, here are decompositions:
- 3 + 4813 = 4816
- 17 + 4799 = 4816
- 23 + 4793 = 4816
- 29 + 4787 = 4816
- 83 + 4733 = 4816
- 113 + 4703 = 4816
- 137 + 4679 = 4816
- 167 + 4649 = 4816
Showing the first eight; more decompositions exist.
