Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12998, here are decompositions:
- 19 + 12979 = 12998
- 31 + 12967 = 12998
- 79 + 12919 = 12998
- 109 + 12889 = 12998
- 157 + 12841 = 12998
- 199 + 12799 = 12998
- 241 + 12757 = 12998
- 277 + 12721 = 12998
Showing the first eight; more decompositions exist.
