find 2 prime numbers that if multiplied would generate a 400 digit number

I'm not sure what you want. 400 is a three-digit number, and 4000 is a four-digit number. I don't think you want a "400 digit number."

Assuming you want a number with a value over 400, this site will be helpful:

I hope this helps. Thanks for asking.
