Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13198, here are decompositions:
- 11 + 13187 = 13198
- 47 + 13151 = 13198
- 71 + 13127 = 13198
- 89 + 13109 = 13198
- 149 + 13049 = 13198
- 191 + 13007 = 13198
- 197 + 13001 = 13198
- 239 + 12959 = 13198
Showing the first eight; more decompositions exist.
