Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528250, here are decompositions:

3 + 528247 = 528250
53 + 528197 = 528250
59 + 528191 = 528250
83 + 528167 = 528250
113 + 528137 = 528250
197 + 528053 = 528250
257 + 527993 = 528250
263 + 527987 = 528250

Showing the first eight; more decompositions exist.
