Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6544, here are decompositions:

23 + 6521 = 6544
53 + 6491 = 6544
71 + 6473 = 6544
191 + 6353 = 6544
227 + 6317 = 6544
233 + 6311 = 6544
257 + 6287 = 6544
281 + 6263 = 6544

Showing the first eight; more decompositions exist.
