How many lines is the input file?

columns 2 and 3: are they always integers; do they have any well-defined min and max possible values; is their disturbution sparse (e.g. is it possible col 3 might have values 336158, and 336159, but then nothing till 491797, or is it likely that most of the gaps inbetween will appear at some point)?
