The reason that falsifiability is useful in science is because scientific conjectures are about how the physical world works and such conjectures can be compared to the was the world is observed to work.
But the theorems of mathematics are not about how the world works.
A mathematical model of how the world works can be shown to be a false representation, but it may still be mathematically perfectly consistent and "true" as a model, just not a good model of that aspect of reality.
Pure mathematicians are, by and large, not so much interested in how well a mathematical structure models some aspect of physical reality, where as applied mathematicians are, by and large, not so much interested in anything else.
