I don't what software forumite Runtime Error used, but it is easy to check:

You asked someone who did not find it, to document how he found it. After you made an extraordinary claim, with no documentation yet.
That seems ... odd. Probably the factor finder used mfaktc or mfakto. We do what we reasonably can to make such information available. Reference information blog An Available software thread in the "New to GIMPS? Start Here" forum's Information and Answers subforum And more, elsewhere.

Factors are absolute proof and the method of their discovery is basically irrelevant. They can be quickly verified to be true (a fraction of a second, IIRC). The PrimeNet server does that for all reported factors before they are entered into the database.
And you have yet to state how you "knew" it to be prime. If you used any of the programs that I mentioned above, there was an error. Fixing any error in the program that produces false prime claims is important to us. Last fiddled with by Uncwilly on 20200620 at 18:16

I apologize for my earlier comment about IP addresses. There have been a few dubious claims recently that seem to be troll posts. Sorry for assuming.
Just to be clear, 156635789 is a prime number. If you wrote a program and found it on your own, good job! It just isn't very big compared to the size of today's known prime numbers. However, the Mersenne number 2^{156635789}1 is not prime because it is divisible by 41094328366458894751937.
