Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520326, here are decompositions:

13 + 520313 = 520326
17 + 520309 = 520326
19 + 520307 = 520326
29 + 520297 = 520326
47 + 520279 = 520326
113 + 520213 = 520326
197 + 520129 = 520326
223 + 520103 = 520326

Showing the first eight; more decompositions exist.
