I have been getting close by implementing FFR4EVA_00's method of [a_2,a_3,a_5...a_p]. It is basically bumping the exponent of all primes < N

But alas, the answer is incorrect.

Did you use a method like this? Or did you go down a different path?

Raising the exponents of the initial "<N" prime list is just a starting point -- from there you need to create prime composites that you can add into the list. Just a matter of determining which composites are worth adding and which are useless. Some of them will be ambiguous -- which is what was tripping me up for the better part of 1.5 days. I ultimately had to do that part manually. I'm not sure if FFR4EVA had a fully automated solution or not, but mine wasn't.
