Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520458, here are decompositions:

7 + 520451 = 520458
11 + 520447 = 520458
31 + 520427 = 520458
47 + 520411 = 520458
79 + 520379 = 520458
89 + 520369 = 520458
97 + 520361 = 520458
101 + 520357 = 520458

Showing the first eight; more decompositions exist.
