Coding challenge

The function isprime(n) will return true is n is prime or false if it isn't. Ex: isprime(10) returns false, but isprime(5) returns true. Write some code to test the Goldbach conjecture, which states that "every even number starting with 6 can be represented as the sum of two odd prime numbers." Note, that the Goldbach conjecture has gone unproven for 200+ years.
