What might link these
A stronger negative correlation after controlling for population and GDP suggests a deeper, potentially structural relationship. Countries that invest more in primary education relative to their GDP might have a more skilled workforce, leading to higher-value exports and a more competitive global economic position. However, it's important to remember this is not a causal link.
Why this is not proof of anything
This is a correlation across countries, not an experiment. It cannot show that either indicator causes the other, and both may simply follow a third thing. The strong negative correlation may still be influenced by unmeasured factors related to a country's development stage or economic structure.
The second figure above repeats the measurement with national population and income held constant. It is the more conservative number: a relationship that largely disappears there was mostly telling you that larger, richer countries have more of most things.
How this was measured
Both indicators were ranked across every country reporting each, and the two rankings compared — ranks rather than raw values, because a handful of very large countries can otherwise manufacture a relationship on their own. The calculation is arithmetic over figures already published on this site; the commentary above is drafted from the two indicator names and the resulting coefficients.
