Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538522, here are decompositions:

3 + 538519 = 538522
11 + 538511 = 538522
41 + 538481 = 538522
191 + 538331 = 538522
239 + 538283 = 538522
263 + 538259 = 538522
359 + 538163 = 538522
401 + 538121 = 538522

Showing the first eight; more decompositions exist.
