Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528438, here are decompositions:

5 + 528433 = 528438
19 + 528419 = 528438
37 + 528401 = 528438
47 + 528391 = 528438
109 + 528329 = 528438
139 + 528299 = 528438
149 + 528289 = 528438
191 + 528247 = 528438

Showing the first eight; more decompositions exist.
