Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528564, here are decompositions:

5 + 528559 = 528564
37 + 528527 = 528564
53 + 528511 = 528564
73 + 528491 = 528564
131 + 528433 = 528564
151 + 528413 = 528564
163 + 528401 = 528564
173 + 528391 = 528564

Showing the first eight; more decompositions exist.
