I found it here. Not sure if that is what Gene was using.

Thanks a lot. Imports without errors in pre-release RPN-65 Pro.

On my iPad Pro, confirmed primality of 999,999,937 in 44 seconds.
To my surprise, replacing steps 3 and 4 (RCL 1 +) with RCL+1 drastically reduced execution time to 25 secs.

To run the program in RPN-67/97, remove the NOP in step 14. Also change step 45 from x=y to x≠y GTO 0 and insert a LBL 0 after 0 RTN.
Running time of the above primality test is 14 seconds.
