Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528398, here are decompositions:

7 + 528391 = 528398
109 + 528289 = 528398
151 + 528247 = 528398
181 + 528217 = 528398
271 + 528127 = 528398
307 + 528091 = 528398
397 + 528001 = 528398
457 + 527941 = 528398

Showing the first eight; more decompositions exist.
