All of a sudden, this is an X-Y problem.  You don't have "two numbers
delimited by a comma".  You have something else entirely.  There are
curly braces now.  I wonder what else is in there.

Is it really JSON?

What's the *actual* goal here?  Where does this input come from, what
does it *really* look like (before any mangling you've already done
on the X-Y path), and what are you trying to do with it?
