It states that every even natural number greater than 2 is the sum of two prime numbers. The conjecture has been shown to hold for all integers less than 4 × 10 18 but remains unproven despite considerable effort.
Goldbach's weak conjecture, every odd number greater than 5 can be expressed as the sum of three primes, is a consequence of Goldbach's conjecture. Ivan Vinogradov proved it for large enough n (Vinogradov's theorem) in 1937, [1] and Harald Helfgott extended this to a full proof of Goldbach's weak conjecture in 2013.
Loss aversion, where the perceived disutility of giving up an object is greater than the utility associated with acquiring it. [ 73 ] (see also Sunk cost fallacy ) Pseudocertainty effect , the tendency to make risk-averse choices if the expected outcome is positive, but make risk-seeking choices to avoid negative outcomes.
Every even number greater than can be represented as the sum of a prime and a square-free number with at most two prime factors. Also in 2022, Bordignon and Valeriia Starichkova [ 9 ] showed that the bound can be lowered to e e 15.85 ≈ 3.6 ⋅ 10 3321634 {\displaystyle e^{e^{15.85}}\approx 3.6\cdot 10^{3321634}} assuming the Generalized ...
Positive numbers: Real numbers that are greater than zero. Negative numbers: Real numbers that are less than zero. Because zero itself has no sign, neither the positive numbers nor the negative numbers include zero. When zero is a possibility, the following terms are often used: Non-negative numbers: Real numbers that are greater than or equal ...
