Bits and Beyond... PRIME NUMBERS Prime numbers have captured the hearts of many mathematicians for centuries. During 18th century, mathematician Christian Goldbach (1690-1764) wrote to Leonhard Euler that he believed it could be shown that every even integer greater than 2 is the sum of 2 primes. For example, 30 = 23+7 and 36 = 13+23. Until now, this conjecture has neither been proved or disproved.
