Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520428, here are decompositions:

5 + 520423 = 520428
17 + 520411 = 520428
19 + 520409 = 520428
47 + 520381 = 520428
59 + 520369 = 520428
67 + 520361 = 520428
71 + 520357 = 520428
79 + 520349 = 520428

Showing the first eight; more decompositions exist.
