Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6916, here are decompositions:
- 5 + 6911 = 6916
- 17 + 6899 = 6916
- 47 + 6869 = 6916
- 53 + 6863 = 6916
- 59 + 6857 = 6916
- 83 + 6833 = 6916
- 89 + 6827 = 6916
- 113 + 6803 = 6916
Showing the first eight; more decompositions exist.
