Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522490, here are decompositions:

11 + 522479 = 522490
41 + 522449 = 522490
107 + 522383 = 522490
167 + 522323 = 522490
173 + 522317 = 522490
239 + 522251 = 522490
251 + 522239 = 522490
257 + 522233 = 522490

Showing the first eight; more decompositions exist.
