Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528538, here are decompositions:

11 + 528527 = 528538
29 + 528509 = 528538
47 + 528491 = 528538
137 + 528401 = 528538
239 + 528299 = 528538
347 + 528191 = 528538
401 + 528137 = 528538
431 + 528107 = 528538

Showing the first eight; more decompositions exist.
