Example: (3,5), (11,13), (17,19), (41,43).

The Twin Prime Conjecture: Still unproven β€” are there infinitely many twin primes?

Answer: Twin Primes

Two prime numbers that differ from each other by exactly 2 are called Twin Primes.

Examples of Twin Prime pairs:

  • (3, 5) β†’ 5 βˆ’ 3 = 2 βœ“
  • (5, 7) β†’ 7 βˆ’ 5 = 2 βœ“
  • (11, 13) β†’ 13 βˆ’ 11 = 2 βœ“
  • (17, 19) β†’ 19 βˆ’ 17 = 2 βœ“
  • (29, 31) β†’ 31 βˆ’ 29 = 2 βœ“
  • (41, 43) β†’ 43 βˆ’ 41 = 2 βœ“

The Twin Prime Conjecture

One of the greatest unsolved problems in mathematics is the Twin Prime Conjecture. It states that there are infinitely many twin prime pairs. Mathematicians believe this is true, but it has never been proven completely. The largest known twin prime pair as of recent research contains hundreds of thousands of digits!
