Solved. I was able to minimize the amount of numbers I generated by finding the square root of the Maybe-Prime, rounded down, and I knew I didn't have to test for factors above that, since I would catch them below that (e.g. if I was testing 90 -> I don't have to worry about testing above 9 (sqrt 90 = 9.49 -> 9) since any factors would be caught if I test 1-9. I don't have to worry about catching 45, since I'll catch it when I test 2. 30 gets caught when I test 3, etc)

 

I also went ahead and excluded the non-2 evens since no reason to mess around with them.

Fun one.  Although, mine might take some time as the number gets larger.
