matlab The Goldbach Conjecture asserts that every even integer greater than 2 can be expressed as the sum of two prime numbers. Write a program that will first generate a random even number on the interval [4, 100], and print its all possible pairs of prime numbers whose sum makes this integer. For example, if n is 50, here are 4 possible pairs: 3 and 47, 7 and 43, 13 and 37, and 19 and 31. The order of the...
