What kind of color code is this?

I'm using a software which exports among others color codes like the following

4278190335
2358853119
656213503
4244695807
545395711
2448883199
7991807

I've never seen such codes before, what kind of color code is this?
Is this even a valid color code? since these are from 7 to 10 digit codes - maybe there are color codes with less or more digits

It is probably just the raw decimal color. 4278190335 in hex is FF 00 00 FF. The last FF is the alpha channel. Each group of 2 digits before corresponds to Red Green and Blue levels. Convert them all to hex and break them into pairs of digits.
