releasing pressure makes something get colder. increasing pressure makes it get hotter.
so where is the increase in pressure coming from that keeps the core hot?
what actually keeps the core hot is radioactive decay on unstable isotopes

600 million years before the Earth becomes too hot to support the carbon cycle.
Safe to say humans will have problems long before that.
although even 1000 years is a very long time with our current rate of technological progress. credible plans exist to change the orbit of the Earth to keep us in the Goldilocks zone.
edit: for the doubters/downvoters.
