hello, I have a question

I worked on it this morning and this is as far as I could get. I prompt user to enter an even integer and if it isn't even the program ends and ask user to please enter an even integer. However, if an even integer is entered than a for loop starts to get all the numbers less than the entered integer except 0 (so there is no division by zero error). Then we get rid of even numbers using modulo. Then we eliminate that odd numbers that aren't prime (like 9, 15, and 27) by using modulo with 3 and 5. Now you have all the prime numbers less than the even integer the user entered. Now all you have to do is find out which two prime numbers add up to the even integer. This should be a good start. Sorry I couldn't finish it!

#prompt user to input an integer
integer = int(input("Please input an even integer:   "))
#if input not even ask user to input even integer
if (integer % 2) != 0:
  print("I am sorry. Please input an even integer: ")
even_integer = integer
#loop through all numbers less than even integer
for i in range(even_integer):
  #only integers greater than 0 to prevent 0 division error
  while i > 0:
    non_zero_integers = i
    #get only odd integers
    if (non_zero_integers % 2) != 0:
      non_even_integers = non_zero_integers
      #get only prime numbers
      if((non_even_integers % 3) & (non_even_integers % 5)) != 0:
        prime_integers = non_even_integers
        print(prime_integers)
    break
