    Goldbach's conjecture is used when studying computation complexity. [36] The connection is made through the Busy Beaver function, where BB (n) is the maximum number of steps taken by any n state Turing machine that halts. There is a 27 state Turing machine that halts if and only if Goldbach's conjecture is false.

    The behaviour of a prime ideal = of A under extension is one of the central problems of algebraic number theory. The following is sometimes useful: [ 22 ] a prime ideal p {\displaystyle {\mathfrak {p}}} is a contraction of a prime ideal if and only if ⁠ p = p e c {\displaystyle {\mathfrak {p}}={\mathfrak {p}}^{ec}} ⁠ .
