Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520386, here are decompositions:

5 + 520381 = 520386
7 + 520379 = 520386
17 + 520369 = 520386
23 + 520363 = 520386
29 + 520357 = 520386
37 + 520349 = 520386
47 + 520339 = 520386
73 + 520313 = 520386

Showing the first eight; more decompositions exist.
