Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6864, here are decompositions:

7 + 6857 = 6864
23 + 6841 = 6864
31 + 6833 = 6864
37 + 6827 = 6864
41 + 6823 = 6864
61 + 6803 = 6864
71 + 6793 = 6864
73 + 6791 = 6864

Showing the first eight; more decompositions exist.
