[ Evenness and Oddness ]  $[$ Prime Numbers and Their Properties ]

In a magic square, the sums of the numbers in each row, each column, and both diagonals are equal. Can a $3 \times 3$ magic square be formed using the first nine prime numbers?
Let the first nine prime numbers be somehow arranged in the cells of a square. Among them, there is exactly one even number - 2. The sum of the numbers in the row containing the two is even (the sum of two odd and one even number). In the rows not containing the two, the sum of the numbers is odd, so the sums of the numbers in some two rows are different, and it is impossible to obtain a magic square.

It is impossible.
