Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6566, here are decompositions:

3 + 6563 = 6566
13 + 6553 = 6566
19 + 6547 = 6566
37 + 6529 = 6566
97 + 6469 = 6566
139 + 6427 = 6566
193 + 6373 = 6566
199 + 6367 = 6566

Showing the first eight; more decompositions exist.
