Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520636, here are decompositions:

3 + 520633 = 520636
5 + 520631 = 520636
29 + 520607 = 520636
47 + 520589 = 520636
89 + 520547 = 520636
107 + 520529 = 520636
227 + 520409 = 520636
257 + 520379 = 520636

Showing the first eight; more decompositions exist.
