David, Eva, and Fred live next to each other and have house numbers that are 2-digit primes.
David: "Our three house numbers are all 2-digit primes."
Eva: "The sum of David's and my house number is the date of Fred's birthday, which was later this month."
Fred: "Funny, the sum of my and Eva's house number is the date of David's birthday, which is today's date."
David: "And the sum of my and Fred's house number is Eva's birthday, which was earlier this month."
