Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13892, here are decompositions:
- 13 + 13879 = 13892
- 19 + 13873 = 13892
- 61 + 13831 = 13892
- 103 + 13789 = 13892
- 163 + 13729 = 13892
- 181 + 13711 = 13892
- 199 + 13693 = 13892
- 211 + 13681 = 13892
Showing the first eight; more decompositions exist.
