Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528442, here are decompositions:

23 + 528419 = 528442
29 + 528413 = 528442
41 + 528401 = 528442
59 + 528383 = 528442
113 + 528329 = 528442
179 + 528263 = 528442
251 + 528191 = 528442
311 + 528131 = 528442

Showing the first eight; more decompositions exist.
