Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012816, here are decompositions:
- 5 + 1012811 = 1012816
- 47 + 1012769 = 1012816
- 53 + 1012763 = 1012816
- 83 + 1012733 = 1012816
- 113 + 1012703 = 1012816
- 137 + 1012679 = 1012816
- 179 + 1012637 = 1012816
- 197 + 1012619 = 1012816
Showing the first eight; more decompositions exist.
