Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528898, here are decompositions:

17 + 528881 = 528898
107 + 528791 = 528898
179 + 528719 = 528898
191 + 528707 = 528898
239 + 528659 = 528898
269 + 528629 = 528898
389 + 528509 = 528898
479 + 528419 = 528898

Showing the first eight; more decompositions exist.
