Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6886, here are decompositions:
- 3 + 6883 = 6886
- 17 + 6869 = 6886
- 23 + 6863 = 6886
- 29 + 6857 = 6886
- 53 + 6833 = 6886
- 59 + 6827 = 6886
- 83 + 6803 = 6886
- 107 + 6779 = 6886
Showing the first eight; more decompositions exist.
