Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13988, here are decompositions:
- 67 + 13921 = 13988
- 109 + 13879 = 13988
- 157 + 13831 = 13988
- 181 + 13807 = 13988
- 199 + 13789 = 13988
- 229 + 13759 = 13988
- 277 + 13711 = 13988
- 307 + 13681 = 13988
Showing the first eight; more decompositions exist.
