Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528518, here are decompositions:

7 + 528511 = 528518
31 + 528487 = 528518
127 + 528391 = 528518
229 + 528289 = 528518
271 + 528247 = 528518
421 + 528097 = 528518
577 + 527941 = 528518
709 + 527809 = 528518

Showing the first eight; more decompositions exist.
