Little Diagonals Sandwich Sudoku

(Published on 29. May 2020, 14:27 by donut and chicken)

Rules:
1. Normal sudoku rules apply. (Place the numbers from 1 to 9 in every row, column, and 3x3 box.)
2. In addition, there are 4 pairs of small diagonals in the grid.
(Colors are for visual aid to tell the pairs of diagonals apart)
Place each number from 1 to 9 once in each pair of diagonals.
NOTE: The two main grid diagonals do not have to contain all the numbers from 1 to 9.
On a square where different pairs of diagonals intersect, that square must be part of all of those diagonals. [4 squares have two intersecting pairs, and square c5r5 is in all 4 pairs.]
3. Normal sandwich sudoku rules apply,
(Each given number outside the grid tells the sum of the numbers between 1 to 9 in its corresponding row/column.)
4. The middle 3x3 box in the grid (highlighted by a thicker box border) is a magic square,
(Each row, column, and the two main diagonals in the box must sum up to the same number)
5. And finally, all squares colored blue can only contain even numbers. [2, 4, 6, and 8]

Enjoy!
The puzzle:
NOTE: This is a revised version of the original puzzle, in which one digit was given. Highlight the hidden text below to reveal the digit and its position.
In the older version of this puzzle; there was a 6 placed in Column 4, Row 6.

Thank you for the nice idea! I removed the digit in the puzzle itself, but left it as hidden text if others want to know the digit that got removed.
