Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522458, here are decompositions:

19 + 522439 = 522458
67 + 522391 = 522458
199 + 522259 = 522458
229 + 522229 = 522458
331 + 522127 = 522458
379 + 522079 = 522458
397 + 522061 = 522458
421 + 522037 = 522458

Showing the first eight; more decompositions exist.
