Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6866, here are decompositions:

3 + 6863 = 6866
37 + 6829 = 6866
43 + 6823 = 6866
73 + 6793 = 6866
103 + 6763 = 6866
157 + 6709 = 6866
163 + 6703 = 6866
193 + 6673 = 6866

Showing the first eight; more decompositions exist.
