Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520388, here are decompositions:

7 + 520381 = 520388
19 + 520369 = 520388
31 + 520357 = 520388
79 + 520309 = 520388
97 + 520291 = 520388
109 + 520279 = 520388
277 + 520111 = 520388
367 + 520021 = 520388

Showing the first eight; more decompositions exist.
