Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520370, here are decompositions:

7 + 520363 = 520370
13 + 520357 = 520370
31 + 520339 = 520370
61 + 520309 = 520370
73 + 520297 = 520370
79 + 520291 = 520370
157 + 520213 = 520370
241 + 520129 = 520370

Showing the first eight; more decompositions exist.
