Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528008, here are decompositions:

7 + 528001 = 528008
67 + 527941 = 528008
79 + 527929 = 528008
127 + 527881 = 528008
139 + 527869 = 528008
157 + 527851 = 528008
199 + 527809 = 528008
307 + 527701 = 528008

Showing the first eight; more decompositions exist.
