Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6556, here are decompositions:

3 + 6553 = 6556
5 + 6551 = 6556
83 + 6473 = 6556
107 + 6449 = 6556
167 + 6389 = 6556
197 + 6359 = 6556
227 + 6329 = 6556
233 + 6323 = 6556

Showing the first eight; more decompositions exist.
