Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522538, here are decompositions:

17 + 522521 = 522538
41 + 522497 = 522538
59 + 522479 = 522538
89 + 522449 = 522538
167 + 522371 = 522538
257 + 522281 = 522538
311 + 522227 = 522538
347 + 522191 = 522538

Showing the first eight; more decompositions exist.
