Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6888, here are decompositions:

5 + 6883 = 6888
17 + 6871 = 6888
19 + 6869 = 6888
31 + 6857 = 6888
47 + 6841 = 6888
59 + 6829 = 6888
61 + 6827 = 6888
97 + 6791 = 6888

Showing the first eight; more decompositions exist.
