$\textsf{\large Detailed}$

   $\texttt{original\_list, modified\_list = \[[2, 5, 12, 23, 45\]], \[[\]]}\\\texttt{for element in original\_list:}\\\texttt{\hspace{1em} if element \% 2 == 0:}\\\texttt{\hspace{2em} modified\_list.append(element + 2)}\\\texttt{\hspace{1em} else:}\\\texttt{\hspace{2em} modified\_list.append(element - 2)}\\\texttt{print(modified\_list)}$
