I think you'll be looking at around 8 to 16mm. The exact distance depends on the conditions expected to be experienced by the board, and what the specific peak voltages are.
You'll certainly want to check with your board house to make sure that they have solder mask that will withstand this voltage, most are good for 500V/mm or so, but you'd likely want a bit more than this to account for deterioration over time. I'm sure others will have some more accurate details. You should check with your local certification company, especially if you're going to market in several countries.
