Let $m = 44121$ and define $n$ to be the largest prime number $n$ such that $2 \le n \le d_{\text{min}}$, where $d_{\text{min}}$ is the smallest divisor of $107113$ that is at least $2$. Let $p(n)$ denote the number of integer partitions of $n$. Compute the remainder when $m \cdot p(n)$ is divided by $89072$.
