Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528900, here are decompositions:

17 + 528883 = 528900
19 + 528881 = 528900
23 + 528877 = 528900
37 + 528863 = 528900
67 + 528833 = 528900
79 + 528821 = 528900
89 + 528811 = 528900
101 + 528799 = 528900

Showing the first eight; more decompositions exist.
