#9 - Prime Sum Sudoku

 Prime Sum Sudoku

 

Standard Sudoku rules apply.
Additionally, every diamond symbol between two cells means that the corresponding digits add up to a prime number (3, 5, 7, 11, 13 or 17).
Conversely, the lack of a diamond symbol between two orthogonally adjacent cells means that the corresponding digits do not add up to a prime number.
