Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520356, here are decompositions:

7 + 520349 = 520356
17 + 520339 = 520356
43 + 520313 = 520356
47 + 520309 = 520356
59 + 520297 = 520356
163 + 520193 = 520356
227 + 520129 = 520356
233 + 520123 = 520356

Showing the first eight; more decompositions exist.
