Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528408, here are decompositions:

5 + 528403 = 528408
7 + 528401 = 528408
17 + 528391 = 528408
79 + 528329 = 528408
109 + 528299 = 528408
191 + 528217 = 528408
211 + 528197 = 528408
241 + 528167 = 528408

Showing the first eight; more decompositions exist.
