Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6616, here are decompositions:

17 + 6599 = 6616
47 + 6569 = 6616
53 + 6563 = 6616
167 + 6449 = 6616
227 + 6389 = 6616
257 + 6359 = 6616
263 + 6353 = 6616
293 + 6323 = 6616

Showing the first eight; more decompositions exist.
