Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520626, here are decompositions:

5 + 520621 = 520626
17 + 520609 = 520626
19 + 520607 = 520626
37 + 520589 = 520626
59 + 520567 = 520626
79 + 520547 = 520626
97 + 520529 = 520626
179 + 520447 = 520626

Showing the first eight; more decompositions exist.
