Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528826, here are decompositions:

3 + 528823 = 528826
5 + 528821 = 528826
47 + 528779 = 528826
107 + 528719 = 528826
167 + 528659 = 528826
197 + 528629 = 528826
317 + 528509 = 528826
443 + 528383 = 528826

Showing the first eight; more decompositions exist.
