What is the amount of energy released when a carbon carbon single bond is broken?

I looked it up in General Chemistry by Whitten, Davis, Peck, and found 347 for the average bond energy of a C-C bond in kJ/mole.
Bond breaking is an energy absorbing process. The question should read:
"What is the amount of energy absorbed when a carbon carbon single bond is broken?"
In a spontaneous decomposition, energy is released because of the formation of new, more stable bonds.
