Goldbach's Conjecture The strong Goldbach's conjecture states every even integer greater than or equal to 4 can be written as a sum of two primes. Write a program that shows that Goldbach's conjecture is true for the even integers between 4 and 2000 inclusively. Store the sums in a file with each sum on its own line. Hint: First find and store all prime numbers less than 2000
