Beryllium carbonate decomposes into Beryllium oxide and Carbon dioxide.

According to Le Chatelier's principle one simply has to store it under a CO2 atmosphere to push the equilibrium to the left.
BeCO3↽−⇀BeO+CO2 in excess
When there is no CO2 atmosphere the equilibrium is pushed to the right, which would be the "normal" case under standard conditions.
