It is impossible for the product of two prime numbers to be prime. It is impossible for the sum of two prime numbers to be prime as long as one of the numbers isn't 2.

The concept of prime numbers has been known since ancient times, with the earliest known reference dating back to around 300 BCE in Euclid's "Elements."

By this definition, prime numbers have existed as long as the natural numbers themselves, which means they are as old as mathematics itself.
Both of those lists are infinitely long.
The sum of three odd numbers will be odd, whether they are prime or not. The sum of three prime numbers can be even as long as one of them is 2.

Probably well before human beings populated the planet. There are species of crickets which breed after a prime number of years so as to ensure they stay out of synch with their predators.

The list is far too long to list here (millions of them); a search on "list of prime numbers" can quickly give you the desired prime numbers.
Leadership has been around ever since Kings, Queens, Prime ministers, and Presidents have started to be chosen around 200 AD.
Both of those lists are infinitely long.
The sum of three odd numbers will be odd, whether they are prime or not. The sum of three prime numbers can be even as long as one of them is 2.
I'm sure there are more than 2 prime numbers that are 400 digits long.
