Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528394, here are decompositions:

3 + 528391 = 528394
11 + 528383 = 528394
131 + 528263 = 528394
197 + 528197 = 528394
227 + 528167 = 528394
257 + 528137 = 528394
263 + 528131 = 528394
353 + 528041 = 528394

Showing the first eight; more decompositions exist.
