CO2 is a relatively stable compound and it would be very hard to thermally decompose it, although not impossible. A quick internet search shows it can be done in precisely controlled environments using lasers (UV absorption to supply the required dissociation energy). But there isn't really a cut and dry temperature.

Work out the enthalpy change for CO2(g) ---> C(g) + O2(g). Then work out the entropy change for the same reaction. Set deltaG = 0 (for the temperature at which this reaction just becoems feasible) and solve:
T = deltaH/deltaS

CO2 is a stable compound. Heating it will not decompose it.

unless you're performing elemental analysis it won't happen
