Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528472, here are decompositions:

3 + 528469 = 528472
53 + 528419 = 528472
59 + 528413 = 528472
71 + 528401 = 528472
89 + 528383 = 528472
173 + 528299 = 528472
281 + 528191 = 528472
419 + 528053 = 528472

Showing the first eight; more decompositions exist.
