Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513528, here are decompositions:

17 + 513511 = 513528
19 + 513509 = 513528
47 + 513481 = 513528
89 + 513439 = 513528
97 + 513431 = 513528
101 + 513427 = 513528
109 + 513419 = 513528
131 + 513397 = 513528

Showing the first eight; more decompositions exist.
