Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11816, here are decompositions:
- 3 + 11813 = 11816
- 37 + 11779 = 11816
- 73 + 11743 = 11816
- 97 + 11719 = 11816
- 127 + 11689 = 11816
- 139 + 11677 = 11816
- 199 + 11617 = 11816
- 223 + 11593 = 11816
Showing the first eight; more decompositions exist.
