Define a prime number to be $\pm$ a usual prime number. Let $C = \{(X,Y,Z) \in \Bbb{Z}^3 : X - Y - Z = 0\}$. Define a composite number to not include $1$. Define $D_{x,y,z} = \{(X,Y,Z)\in C: X \in x\Bbb{Z}, \dots, Z \in z\Bbb{Z}\}$. It forms a $\Bbb{Z}$-submodule of $C$. Now take:  \pi: C \to...

I have also made edits to ensure that the question is not subjective.
With guided feedback from other users who have been on this site for a while.

I understand @Peter
I will delete the question.
May someone please provide the final vote to close. Thank you.

@bumblebee You can delete your own questions, even if they are not closed.
