Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6870, here are decompositions:

7 + 6863 = 6870
13 + 6857 = 6870
29 + 6841 = 6870
37 + 6833 = 6870
41 + 6829 = 6870
43 + 6827 = 6870
47 + 6823 = 6870
67 + 6803 = 6870

Showing the first eight; more decompositions exist.
