Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528166, here are decompositions:

3 + 528163 = 528166
29 + 528137 = 528166
59 + 528107 = 528166
113 + 528053 = 528166
173 + 527993 = 528166
179 + 527987 = 528166
257 + 527909 = 528166
269 + 527897 = 528166

Showing the first eight; more decompositions exist.
