Formation is just one part of the equation. On the other side there's an additional C-C bond per segment of the hydrocarbon chain longer than methane, which you need to break during combustion.

For carbon, it's graphite with its C-C bonds. I did neglect the C-H bond enthalpy, but it's close enough to the C-C bond energy to matter too much.
