Prime Number Search
Search for prime numbers near a specific number. A prime number is an integer greater than 1 that is only divisble by 1 and itself. The search number can be arbitrarily large, but it may take a while to compute. It will search until at least two primes have been found, verified by 40 rounds of the Miller-Rabin test.
Enter a number, or an expression like 2^89-1, and click Search.
