Paddy and Gail Millar from Ballymena won GBP2 million on the Friday, August 10 draw of EuroMillions.
While choosing his numbers, Paddy included the age of his wife and mistakenly wrote 48 instead of 49.
"It's the best mistake I've made in my life," he said.
The couple has no plans yet on what to do with the winnings.
