One way to find them is with a Sieve of Eratosthenes, and Golbach's Conjecture states that every number greater than 2 can be written as the sum of two of these numbers.

Euler proved that the sum of their reciprocals diverges, while the fundamental theorem of arithmetic states that all natural numbers can be uniquely factorized into them. For ten points, name these numbers divisible only by one and themselves.
