Summary:
In a letter written to Landau in 1935, Schur stated that for any integer $t>2$, there are primes $p_{1}<p_{2}<\cdots <p_{t}$ such that $p_{1}+p_{2}>p_{t}$. In this note, we use the Prime Number Theorem and extend Schur's result to show that for any integers $t\ge k \ge 1$ and real $\epsilon >0$, there exist primes $p_{1}<p_{2}<\cdots <p_{t}$ such that \[ p_{1}+p_{2}+\cdots +p_{k}>(k-\epsilon )p_{t}. \]
