Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2986, here are decompositions:
- 17 + 2969 = 2986
- 23 + 2963 = 2986
- 29 + 2957 = 2986
- 47 + 2939 = 2986
- 59 + 2927 = 2986
- 83 + 2903 = 2986
- 89 + 2897 = 2986
- 107 + 2879 = 2986
Showing the first eight; more decompositions exist.
