Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528274, here are decompositions:

11 + 528263 = 528274
83 + 528191 = 528274
107 + 528167 = 528274
137 + 528137 = 528274
167 + 528107 = 528274
233 + 528041 = 528274
281 + 527993 = 528274
293 + 527981 = 528274

Showing the first eight; more decompositions exist.
