Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528822, here are decompositions:

11 + 528811 = 528822
23 + 528799 = 528822
31 + 528791 = 528822
43 + 528779 = 528822
59 + 528763 = 528822
103 + 528719 = 528822
113 + 528709 = 528822
131 + 528691 = 528822

Showing the first eight; more decompositions exist.
