Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13814, here are decompositions:
- 7 + 13807 = 13814
- 103 + 13711 = 13814
- 127 + 13687 = 13814
- 181 + 13633 = 13814
- 223 + 13591 = 13814
- 277 + 13537 = 13814
- 337 + 13477 = 13814
- 373 + 13441 = 13814
Showing the first eight; more decompositions exist.
