An anti magic square is an N×N grid containing the integers from 1 through N^2, such that the sum of each row, column, and main diagonal is a different number, and those sums form a consecutive sequence of integers.

There are no 3×3 anti magic squares, but there are some that are close in that the sequence of sums is consecutive except for one missing value.

Determine a 3×3 near anti magic square in which the three digit number represented by the top left (hundreds position) to bottom right (units position) main diagonal is a minimum. Present your answer as a 3×3 grid containing the digits 1 through 9.
