How can I convert PascalCase to split words?

Question

I have variables containing text such as:

ShowSummary
ShowDetails
AccountDetails

Is there a simple way function / method in C# that I can apply to these variables to yield:

"Show Summary"
"Show Details"
"Account Details"

I was wondering about an extension method but I've never coded one and I am not sure where to start.
