Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528558, here are decompositions:

31 + 528527 = 528558
47 + 528511 = 528558
67 + 528491 = 528558
71 + 528487 = 528558
89 + 528469 = 528558
139 + 528419 = 528558
157 + 528401 = 528558
167 + 528391 = 528558

Showing the first eight; more decompositions exist.
