They are Robert (Bob) and Jeanne Gagnon.
Gagnon said that she opted for the 30-year payout rather than the lump sum, because she will get to keep more the money over the long term.
"That means I have to live until I'm 90-something now," she said with a laugh.
The couple learned of their luck after their son called the lottery hotline following last week's drawing.
"When he told me, I asked if he was kidding," Gagnon said. She then woke up her husband to tell him.
"I'm glad," said her husband. "It's about time we got some good news."
The couple has been married for 47 years. Gagnon said that he is from St. Agatha and his wife from St. David.
Gagnon said that his wife always picks the numbers and has been playing since Megabucks started. Winning the jackpot has not deterred her from continuing to play either, as she purchased more tickets before leaving the store on Thursday morning.
"You can't win if you don't play," she said.
The winning numbers were drawn Feb. 19 at Bob's Neighborhood Store in Madawaska with only a single winning ticket, according to the Maine Lottery.
Pete Williams owns the store with his wife Susan. As owners of the store that sold the winning ticket, the couple can collect a bonus of one percent of the winnings, up to $30,000.
