I need a function that returns the smallest prime number p smaller than 100,000 such that (p + n) is also prime, where n is a scalar integer and is the sole input argument to the function

Write a function called prime_pairs that returns the smallest prime number p smaller than 100,000 such that (p + n) is also prime, where n is a scalar integer and is the sole input argument to the function. If no such number exists, then the function returns -1. You may use the built-in functions, primes and isprime.

For simple code refer this and ask if you have any query: http://farzicoders.blogspot.in/2015/08/write-function-called-primepairs-that.html

"simple code" with:
- poorly named variables: for i=1:l
- superfluous intermediate variables: flag
- superfluous loops when code vectorization would be neater.
- superfluous return statements.
