Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528588, here are decompositions:

29 + 528559 = 528588
61 + 528527 = 528588
79 + 528509 = 528588
97 + 528491 = 528588
101 + 528487 = 528588
197 + 528391 = 528588
271 + 528317 = 528588
397 + 528191 = 528588

Showing the first eight; more decompositions exist.
