Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13118, here are decompositions:
- 19 + 13099 = 13118
- 109 + 13009 = 13118
- 139 + 12979 = 13118
- 151 + 12967 = 13118
- 199 + 12919 = 13118
- 211 + 12907 = 13118
- 229 + 12889 = 13118
- 277 + 12841 = 13118
Showing the first eight; more decompositions exist.
