Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13982, here are decompositions:
- 19 + 13963 = 13982
- 61 + 13921 = 13982
- 79 + 13903 = 13982
- 103 + 13879 = 13982
- 109 + 13873 = 13982
- 151 + 13831 = 13982
- 193 + 13789 = 13982
- 223 + 13759 = 13982
Showing the first eight; more decompositions exist.
