This is my very first puzzle, hope you enjoy!

• Normal sudoku rules apply.
• In this puzzle, some cells are Prime Cells. A cell is considered a Prime Cell if its row number, column number, box number, as well as the digit it contains, together sum to a prime number.
• Clues outside the grid indicate the sum of the digits in all Prime Cells seen from that side in a row or column before encountering a non-Prime cell.
• The small clues in the top left corner of cages indicate the sum of all Prime Cells within the cage. Digits may repeat within cages if otherwise allowed by the rules of sudoku.
• Cells indicated with a square are even, cells indicated with a circle are odd.
