Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13208, here are decompositions:
- 31 + 13177 = 13208
- 37 + 13171 = 13208
- 61 + 13147 = 13208
- 109 + 13099 = 13208
- 199 + 13009 = 13208
- 229 + 12979 = 13208
- 241 + 12967 = 13208
- 367 + 12841 = 13208
Showing the first eight; more decompositions exist.
