X Abstract

Translation of Utrum hic numerus: 1000009 sit primus, nec ne, inquiritur, Nova Acta Academiae Scientarum Imperialis Petropolitinae 10 (1797), 63-73; E699 in the Enestrom index. In this paper Euler shows that 1000009 is not prime by showing that it can be decomposed into the sum of two squares in more than one way, correcting a published list of primes which had included 1000009. He further shows that 1000081 is prime, by showing that it can only be decomposed into the sum of two squares in one way.
