Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522728, here are decompositions:

67 + 522661 = 522728
127 + 522601 = 522728
211 + 522517 = 522728
337 + 522391 = 522728
439 + 522289 = 522728
499 + 522229 = 522728
571 + 522157 = 522728
601 + 522127 = 522728

Showing the first eight; more decompositions exist.
