Can a vacuum environment lower the boiling point of water?

[gfought]

A liquid in a vacuum environment has a lower boiling point than when the liquid is at atmospheric pressure



Thermal decomposition, or thermolysis, is a chemical decomposition caused by heat.
Water, when heated to well over 2000 °C, decomposes to its constituent elements:

could a a vacuum be created to lower the decomposition point?

No, I do not believe so. Or at least it won't be significant when compared to standard pressure as those temperatures u ~= h.
