How could I decrease the boiling point of a substance without changing the pressure of the liquid?

This can be done by mixing different liquids of different boiling points together. For instance, if you mix ethyl alcohol and water, the liquid will boil at a boiling point somewhere in between about 78 degrees C for alcohol and 100 degrees C. for water. Chemistry books have charts listing different boiling points. Look up minimum boiling mixtures, or azeotropes in the index. Good luck!
