Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528454, here are decompositions:

41 + 528413 = 528454
53 + 528401 = 528454
71 + 528383 = 528454
137 + 528317 = 528454
191 + 528263 = 528454
257 + 528197 = 528454
263 + 528191 = 528454
317 + 528137 = 528454

Showing the first eight; more decompositions exist.
