Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528532, here are decompositions:

5 + 528527 = 528532
23 + 528509 = 528532
41 + 528491 = 528532
113 + 528419 = 528532
131 + 528401 = 528532
149 + 528383 = 528532
233 + 528299 = 528532
269 + 528263 = 528532

Showing the first eight; more decompositions exist.
