Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13898, here are decompositions:
- 19 + 13879 = 13898
- 67 + 13831 = 13898
- 109 + 13789 = 13898
- 139 + 13759 = 13898
- 211 + 13687 = 13898
- 229 + 13669 = 13898
- 271 + 13627 = 13898
- 307 + 13591 = 13898
Showing the first eight; more decompositions exist.
