Windows Server 2012 Essentials - limits on shrink volume

I'm trying to shrink c volume to add another simple one. I want to shrink C from 837GB to 200GB. C now has 823GB free.

The shrink dialog shows:

Total size before shrink in MP:            857857
Size of available shrink space in MB:      425878
Enter the amount of space to shrink in MB: 425878
Total size after shrink in MB:             431979
