Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2798, here are decompositions:
- 7 + 2791 = 2798
- 31 + 2767 = 2798
- 67 + 2731 = 2798
- 79 + 2719 = 2798
- 109 + 2689 = 2798
- 127 + 2671 = 2798
- 139 + 2659 = 2798
- 151 + 2647 = 2798
Showing the first eight; more decompositions exist.
