Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520392, here are decompositions:

11 + 520381 = 520392
13 + 520379 = 520392
23 + 520369 = 520392
29 + 520363 = 520392
31 + 520361 = 520392
43 + 520349 = 520392
53 + 520339 = 520392
79 + 520313 = 520392

Showing the first eight; more decompositions exist.
