Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13838, here are decompositions:
- 7 + 13831 = 13838
- 31 + 13807 = 13838
- 79 + 13759 = 13838
- 109 + 13729 = 13838
- 127 + 13711 = 13838
- 151 + 13687 = 13838
- 157 + 13681 = 13838
- 211 + 13627 = 13838
Showing the first eight; more decompositions exist.
