Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13844, here are decompositions:
- 3 + 13841 = 13844
- 13 + 13831 = 13844
- 37 + 13807 = 13844
- 151 + 13693 = 13844
- 157 + 13687 = 13844
- 163 + 13681 = 13844
- 211 + 13633 = 13844
- 277 + 13567 = 13844
Showing the first eight; more decompositions exist.
