Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6844, here are decompositions:
- 3 + 6841 = 6844
- 11 + 6833 = 6844
- 17 + 6827 = 6844
- 41 + 6803 = 6844
- 53 + 6791 = 6844
- 83 + 6761 = 6844
- 107 + 6737 = 6844
- 191 + 6653 = 6844
Showing the first eight; more decompositions exist.
