Morphology
The meaning is directly compositional: 'prove' (establish by evidence) combined with 'otherwise' (in a different or opposite way) yields 'show that a different/opposite result is true.' The particle 'otherwise' clearly signals an alternative to the prior claim and this pattern is cross-linguistically common, so a B1 learner who knows both words would readily infer the MWE meaning.
Etymology
Prove otherwise paints a simple picture: the word prove means 'to show' and otherwise means 'in a different way', so when facts prove otherwise they show that an earlier idea is actually different or the opposite. That's why it means 'to show the opposite'.
