A Zany Zipper snake is heading to the Sudoku variant museum to check out the new exhibits. It enters the museum through one of the 4 exits (Corners) and wants to visit every exhibit (Box) exactly once, then leave the museum by a different exit.

The snake consists of a single path of orthogonally connected cells that never touches itself orthogonally (diagonally is fine).
Pairs of digits along the snake an equal distance from the middle of the snake must sum to the same number. If the snake is of odd length, the middle digit is equal to that sum.

Solve the sudoku such that there exists a unique path for the snake through the museum.

All standard variant rules apply.
