The sum of the first two rows equals the sum of the bottom two rows and the sum of the squares of the numbers in the first two rows equals the sum of the squares of the numbers in the bottom two rows.  Likewise for the columns. 
 
The same is true for the numbers of the first and third rows (and the sum of their squares) as respects the numbers of the second and fourth rows.  Likewise for the columns.
 
The sum of one set of symmetrically placed numbers, their squares and cubes equals the sum of the other set of symmetrically placed numbers, their squares and cubes.
