  In this paper, we consider the problem of decomposing the augmented cube
$AQ_n$ into two spanning, regular, connected and pancyclic subgraphs. We prove
that for $ n \geq 4$ and $ 2n - 1 = n_1 + n_2 $ with $ n_1, n_2 \geq 2,$ the
augmented cube $ AQ_n$ can be decomposed into two spanning subgraphs $ H_1$ and
$ H_2$ such that each $ H_i$ is $n_i$-regular and $n_i$-connected. Moreover,
$H_i$ is $4$-pancyclic if $ n_i \geq 3.$
