Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6900, here are decompositions:

17 + 6883 = 6900
29 + 6871 = 6900
31 + 6869 = 6900
37 + 6863 = 6900
43 + 6857 = 6900
59 + 6841 = 6900
67 + 6833 = 6900
71 + 6829 = 6900

Showing the first eight; more decompositions exist.
