The man, who wishes to keep his family’s win private, purchased the winning ticket at the Eason store in Mahon Point Shopping Centre on the day of the draw.
Today, the family made the trip to Dublin to claim the big win.
As a lifetime National Lottery player, the man joked that he was always convinced that he would win big one day:
"I have always known that I’d end up at Lottery HQ collecting a big cheque.
"Today really is a dream come true for me and what better way to celebrate this win than to share it with my family.
"We certainly won’t be going mad buying any fancy cars or anything like that.
"The family are all at different stages of their own lives so having this prize to share equally among us will enable us to do our own thing and give us all the opportunity to make some nice changes in our lives," he said.
Describing how they found out about their lucky win, one of the winning family members said:
"It was really weird.
"We were having a cup of tea in the kitchen the morning after the draw and my dad told me that he had a winning ticket in the EuroMillions draw from the previous night’s draw.
"And this was ever before we heard the news of the win in Mahon.
"He was just absolutely convinced.
"I checked my phone and lo and behold there was a winning ticket sold in Cork and he was laughing away to himself, he just knew it was him.
"We popped off to our local shop shortly after to have the ticket checked but in truth, we probably didn’t even need to check it because he was so certain it was our ticket.
"There’s certainly some truth in the power of positive thinking."
So far this year, a total of €246 million has been won by EuroMillions players in Ireland including an incredible 24 winners of the €500,000 EuroMillion Plus top prize.
Tonight’s Lotto jackpot is an estimated €4.5 million.
