Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2982, here are decompositions:
- 11 + 2971 = 2982
- 13 + 2969 = 2982
- 19 + 2963 = 2982
- 29 + 2953 = 2982
- 43 + 2939 = 2982
- 73 + 2909 = 2982
- 79 + 2903 = 2982
- 103 + 2879 = 2982
Showing the first eight; more decompositions exist.
