Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13028, here are decompositions:
- 19 + 13009 = 13028
- 61 + 12967 = 13028
- 109 + 12919 = 13028
- 139 + 12889 = 13028
- 199 + 12829 = 13028
- 229 + 12799 = 13028
- 271 + 12757 = 13028
- 307 + 12721 = 13028
Showing the first eight; more decompositions exist.
