Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13828, here are decompositions:
- 29 + 13799 = 13828
- 47 + 13781 = 13828
- 71 + 13757 = 13828
- 107 + 13721 = 13828
- 131 + 13697 = 13828
- 137 + 13691 = 13828
- 149 + 13679 = 13828
- 179 + 13649 = 13828
Showing the first eight; more decompositions exist.
