Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522508, here are decompositions:

11 + 522497 = 522508
29 + 522479 = 522508
59 + 522449 = 522508
137 + 522371 = 522508
191 + 522317 = 522508
227 + 522281 = 522508
257 + 522251 = 522508
269 + 522239 = 522508

Showing the first eight; more decompositions exist.
