Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528328, here are decompositions:

11 + 528317 = 528328
29 + 528299 = 528328
131 + 528197 = 528328
137 + 528191 = 528328
191 + 528137 = 528328
197 + 528131 = 528328
347 + 527981 = 528328
419 + 527909 = 528328

Showing the first eight; more decompositions exist.
