Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528254, here are decompositions:

7 + 528247 = 528254
31 + 528223 = 528254
37 + 528217 = 528254
127 + 528127 = 528254
157 + 528097 = 528254
163 + 528091 = 528254
211 + 528043 = 528254
241 + 528013 = 528254

Showing the first eight; more decompositions exist.
