This is actually extremely common. It has nothing to do with 2 seats being more expensive than 1, but has to do with the fact that there are probably a dozen economy fare buckets, each more expensive than the previous, with only a certain number of seats left in each one.
For example, a flight may have 20 physical seats left in economy, but they are broken down like this:
Fare group X: 2 seats @ $700
Fare group Y: 1 seat @ $800
Fare group Z: 17 seats @ $900
In this case, one seat would be $700, two seats would be $1400, three seats would be $2200, and four seats would be $3100, if that makes sense.
