Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520398, here are decompositions:

5 + 520393 = 520398
17 + 520381 = 520398
19 + 520379 = 520398
29 + 520369 = 520398
37 + 520361 = 520398
41 + 520357 = 520398
59 + 520339 = 520398
89 + 520309 = 520398

Showing the first eight; more decompositions exist.
