Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528270, here are decompositions:

7 + 528263 = 528270
23 + 528247 = 528270
47 + 528223 = 528270
53 + 528217 = 528270
73 + 528197 = 528270
79 + 528191 = 528270
103 + 528167 = 528270
107 + 528163 = 528270

Showing the first eight; more decompositions exist.
