Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6858, here are decompositions:

17 + 6841 = 6858
29 + 6829 = 6858
31 + 6827 = 6858
67 + 6791 = 6858
79 + 6779 = 6858
97 + 6761 = 6858
139 + 6719 = 6858
149 + 6709 = 6858

Showing the first eight; more decompositions exist.
