Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528020, here are decompositions:

7 + 528013 = 528020
19 + 528001 = 528020
37 + 527983 = 528020
79 + 527941 = 528020
139 + 527881 = 528020
151 + 527869 = 528020
211 + 527809 = 528020
271 + 527749 = 528020

Showing the first eight; more decompositions exist.
