Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13790, here are decompositions:
- 31 + 13759 = 13790
- 61 + 13729 = 13790
- 67 + 13723 = 13790
- 79 + 13711 = 13790
- 97 + 13693 = 13790
- 103 + 13687 = 13790
- 109 + 13681 = 13790
- 157 + 13633 = 13790
Showing the first eight; more decompositions exist.
