Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528922, here are decompositions:

11 + 528911 = 528922
41 + 528881 = 528922
59 + 528863 = 528922
89 + 528833 = 528922
101 + 528821 = 528922
131 + 528791 = 528922
263 + 528659 = 528922
293 + 528629 = 528922

Showing the first eight; more decompositions exist.
