Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528238, here are decompositions:

41 + 528197 = 528238
47 + 528191 = 528238
71 + 528167 = 528238
101 + 528137 = 528238
107 + 528131 = 528238
131 + 528107 = 528238
197 + 528041 = 528238
251 + 527987 = 528238

Showing the first eight; more decompositions exist.
