Killer Sudoku two-cell sum combinations

A complete reference chart of the nonrepeating digit pairs for two-cell Killer Sudoku cages, covering sums 3–17.

How to read this diagram

Find the cage total in the left column. The right column lists all unordered pairs of different digits from 1–9 with that total.

For example, a two-cell cage totaling 10 permits 1+9, 2+8, 3+7 or 4+6. A pair like 5+5 is excluded because digits cannot repeat inside a cage. The chart contains all 36 possible distinct-digit pairs.
