Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13970, here are decompositions:
- 3 + 13967 = 13970
- 7 + 13963 = 13970
- 37 + 13933 = 13970
- 67 + 13903 = 13970
- 97 + 13873 = 13970
- 139 + 13831 = 13970
- 163 + 13807 = 13970
- 181 + 13789 = 13970
Showing the first eight; more decompositions exist.
