Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522638, here are decompositions:

37 + 522601 = 522638
97 + 522541 = 522638
199 + 522439 = 522638
229 + 522409 = 522638
349 + 522289 = 522638
379 + 522259 = 522638
409 + 522229 = 522638
439 + 522199 = 522638

Showing the first eight; more decompositions exist.
