Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13998, here are decompositions:
- 31 + 13967 = 13998
- 67 + 13931 = 13998
- 97 + 13901 = 13998
- 139 + 13859 = 13998
- 157 + 13841 = 13998
- 167 + 13831 = 13998
- 191 + 13807 = 13998
- 199 + 13799 = 13998
Showing the first eight; more decompositions exist.
