Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528838, here are decompositions:

5 + 528833 = 528838
17 + 528821 = 528838
47 + 528791 = 528838
59 + 528779 = 528838
131 + 528707 = 528838
179 + 528659 = 528838
227 + 528611 = 528838
311 + 528527 = 528838

Showing the first eight; more decompositions exist.
