re(2): Solution? - confirmation by Math Man)
Right. I set out to recreate the list in your puzzle w/ J's prescription using brute force, and had success. I did raise the possibility of interlopers being missed in my extended list, given my program's limits and yes - there are some large ones, as seen in A291460. For succinct programming examples with better inclusiveness see A291460's list, where Mathematica, Python, and other languages are shown. Thanks for the observations.
