Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520928, here are decompositions:

7 + 520921 = 520928
61 + 520867 = 520928
181 + 520747 = 520928
211 + 520717 = 520928
229 + 520699 = 520928
307 + 520621 = 520928
379 + 520549 = 520928
547 + 520381 = 520928

Showing the first eight; more decompositions exist.
