Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6904, here are decompositions:

5 + 6899 = 6904
41 + 6863 = 6904
47 + 6857 = 6904
71 + 6833 = 6904
101 + 6803 = 6904
113 + 6791 = 6904
167 + 6737 = 6904
251 + 6653 = 6904

Showing the first eight; more decompositions exist.
