Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528450, here are decompositions:

17 + 528433 = 528450
31 + 528419 = 528450
37 + 528413 = 528450
47 + 528403 = 528450
59 + 528391 = 528450
67 + 528383 = 528450
137 + 528313 = 528450
151 + 528299 = 528450

Showing the first eight; more decompositions exist.
