Although I haven't ever scaled it that high, I've had a lot of luck using
Gearman (mod_gearman) to make Nagios horizontally scalable.

It allows you to use Nagios itself only as a scheduler and reporting UI,
and offload all of the actual probing to other servers.  There'll be a
theoretical limit to the amount of scale you get get out of that due to
relying on a single Nagios instance to schedule checks and receive reports
of success, but I imagine it's much higher than your current requirements.
