Goldbach decomposition

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.
