How to carry out the reaction of decomposition of kMnO4 into something unknown and O2?

Let’s carry out the reaction of dissociation of potassium permanganate, chemical formula K2MnO4.

In order to carry out this reaction, potassium permanganate should be heated. Under the influence of temperature, potassium permanganate decomposes into magnesium oxide and oxygen.

2 KMnO4 = K2MnO4 + MnO2 + O2
