Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6528, here are decompositions:

7 + 6521 = 6528
37 + 6491 = 6528
47 + 6481 = 6528
59 + 6469 = 6528
79 + 6449 = 6528
101 + 6427 = 6528
107 + 6421 = 6528
131 + 6397 = 6528

Showing the first eight; more decompositions exist.
