Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6538, here are decompositions:

17 + 6521 = 6538
47 + 6491 = 6538
89 + 6449 = 6538
149 + 6389 = 6538
179 + 6359 = 6538
227 + 6311 = 6538
239 + 6299 = 6538
251 + 6287 = 6538

Showing the first eight; more decompositions exist.
