Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6526, here are decompositions:

5 + 6521 = 6526
53 + 6473 = 6526
137 + 6389 = 6526
167 + 6359 = 6526
173 + 6353 = 6526
197 + 6329 = 6526
227 + 6299 = 6526
239 + 6287 = 6526

Showing the first eight; more decompositions exist.
