Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528914, here are decompositions:

3 + 528911 = 528914
31 + 528883 = 528914
37 + 528877 = 528914
103 + 528811 = 528914
151 + 528763 = 528914
223 + 528691 = 528914
241 + 528673 = 528914
283 + 528631 = 528914

Showing the first eight; more decompositions exist.
