Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6856, here are decompositions:
- 23 + 6833 = 6856
- 29 + 6827 = 6856
- 53 + 6803 = 6856
- 137 + 6719 = 6856
- 167 + 6689 = 6856
- 197 + 6659 = 6856
- 257 + 6599 = 6856
- 293 + 6563 = 6856
Showing the first eight; more decompositions exist.
