PowerShell output random numbers to csv. CSV full of empty lines

Actually 2 part question here. The code below outputs nothing but 1000 blank lines to the csv. I'm just trying to output a random range of numbers to a csv and I actually need to follow up with 4 more columns of randomly generated numbers like this first attempt so the second part of this is after getting this first issue resolved how would I direct the next ranges to the other columns?

Get-Random -Count 998 -InputObject (8000..8999) | Export-Csv -Path SingleColumn.csv -NoTypeInformation
