Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513526, here are decompositions:

17 + 513509 = 513526
47 + 513479 = 513526
53 + 513473 = 513526
107 + 513419 = 513526
173 + 513353 = 513526
179 + 513347 = 513526
257 + 513269 = 513526
269 + 513257 = 513526

Showing the first eight; more decompositions exist.
