Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520420, here are decompositions:

11 + 520409 = 520420
41 + 520379 = 520420
59 + 520361 = 520420
71 + 520349 = 520420
107 + 520313 = 520420
113 + 520307 = 520420
179 + 520241 = 520420
227 + 520193 = 520420

Showing the first eight; more decompositions exist.
