Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528802, here are decompositions:

3 + 528799 = 528802
11 + 528791 = 528802
23 + 528779 = 528802
83 + 528719 = 528802
173 + 528629 = 528802
179 + 528623 = 528802
191 + 528611 = 528802
293 + 528509 = 528802

Showing the first eight; more decompositions exist.
