Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2918, here are decompositions:
- 31 + 2887 = 2918
- 61 + 2857 = 2918
- 67 + 2851 = 2918
- 127 + 2791 = 2918
- 151 + 2767 = 2918
- 199 + 2719 = 2918
- 211 + 2707 = 2918
- 229 + 2689 = 2918
Showing the first eight; more decompositions exist.
