Get Smart
Maxwell Smart (Agent 86) was trying to get a coded message to his girlfriend (Agent 99). He had to type into his shoe phone, her agent number 99 as the sum of two prime numbers. How many different ways could Max do this?
Hint
Don't spend TOO long searching!Answer
Just one way. As all prime numbers except 2 are odd, and the sum of any two odd numbers is even, then the sum must contain 2 as one of the numbers since 99 is odd. Therefore, 2 + 97 is the only way.Hide Hint Show Hint Hide Answer Show Answer

good one
I say 2 ways: 2+97 and 97+2.
great.... in many ways
Delightful - a great teaching tool on primes and odd/even sums in a fun puzzle. Thank you.
enjoyable. seems appropriate for reviewing prime numbers. Not overly challenging.
I liked this brain teaser a lot!! I was thinking to hard, at first.
not terrible. i would suggest though that you had put in the whole answer. you forgot to put in how you got the number 97. sorry if this seems offensive though!
Cool! I haven't thought about Max and 99 in a long time. Thanks for bringing back some fun memories!!
easy. I love watching "Get Smart". Siegfried is awesome. good teaser
