Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520530, here are decompositions:

79 + 520451 = 520530
83 + 520447 = 520530
97 + 520433 = 520530
103 + 520427 = 520530
107 + 520423 = 520530
137 + 520393 = 520530
149 + 520381 = 520530
151 + 520379 = 520530

Showing the first eight; more decompositions exist.
