Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522528, here are decompositions:

5 + 522523 = 522528
7 + 522521 = 522528
11 + 522517 = 522528
31 + 522497 = 522528
59 + 522469 = 522528
79 + 522449 = 522528
89 + 522439 = 522528
137 + 522391 = 522528

Showing the first eight; more decompositions exist.
