Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528842, here are decompositions:

19 + 528823 = 528842
31 + 528811 = 528842
43 + 528799 = 528842
79 + 528763 = 528842
151 + 528691 = 528842
163 + 528679 = 528842
211 + 528631 = 528842
283 + 528559 = 528842

Showing the first eight; more decompositions exist.
