Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528858, here are decompositions:

37 + 528821 = 528858
47 + 528811 = 528858
59 + 528799 = 528858
67 + 528791 = 528858
79 + 528779 = 528858
139 + 528719 = 528858
149 + 528709 = 528858
151 + 528707 = 528858

Showing the first eight; more decompositions exist.
