Content Summary
Euler shows that 1,000,009 is not prime by showing that it can be written as the sum of two squares in more than one way. This corrected a published list of primes that had included 1,000,009. He also shows that 1,000,081 is prime by showing that it can be written as the sum of two squares in only one way. (Based on Jordan Bell's translation abstract.)
