Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522428, here are decompositions:

19 + 522409 = 522428
37 + 522391 = 522428
139 + 522289 = 522428
199 + 522229 = 522428
229 + 522199 = 522428
271 + 522157 = 522428
349 + 522079 = 522428
367 + 522061 = 522428

Showing the first eight; more decompositions exist.
