Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528404, here are decompositions:

3 + 528401 = 528404
13 + 528391 = 528404
31 + 528373 = 528404
157 + 528247 = 528404
181 + 528223 = 528404
241 + 528163 = 528404
277 + 528127 = 528404
307 + 528097 = 528404

Showing the first eight; more decompositions exist.
