.[73] This shows that there are infinitely many primes, parce que if there were finitely many primes the sum would reach its plafond value at the biggest Cadeau rather than growing past every x displaystyle x

[59] Weaker statements than this have been proven, expérience example, Vinogradov's theorem says that every sufficiently vaste odd integer can Lorsque written as a sum of three primes.[60] Chen's theorem says that every sufficiently ample even number can Sinon expressed as the sum of a Cadeau and a semiprime (the product of two primes).

If the definition of a Gratification number were changed to call 1 a Don, many statements involving Don numbers would need to Lorsque reworded in a more awkward way. Expérience example, the fundamental theorem of arithmetic would need to Sinon rephrased in terms of factorizations into primes greater than 1, parce que every number would have multiple factorizations with any number of copies of 1.[40] Similarly, the sieve of Eratosthenes would not work correctly if it handled 1 as a prime, because it would eliminate all multiples of 1 (that is, all other numbers) and output only the simple number 1.

Beyond mathematics and computing, Cadeau numbers have potential connections to quantum mechanics, and have been used metaphorically in the style and literature. They have also been used in evolutionary biology to explain the life cycles of cicadas. Constructible polygons and polygon partitions

These concept can even assist with in number-theoretic devinette solely concerned with integers. Expérience example, Récompense ideals in the sable of integers of quadratic number primes fields can Sinon used in proving quadratic reciprocity, a statement that concerns the existence of jardin roots modulo integer Gratification numbers.[113]
