Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528312, here are decompositions:

13 + 528299 = 528312
23 + 528289 = 528312
89 + 528223 = 528312
149 + 528163 = 528312
181 + 528131 = 528312
269 + 528043 = 528312
271 + 528041 = 528312
311 + 528001 = 528312

Showing the first eight; more decompositions exist.
