Goldbach Conjecture

[DrD]

Thanks for your ideas, Theresa. I had to edit my opening post, as something went crazy with the text there.

I've also included a different approach, of many I'm sure, that builds the Goldbach composition and partitions. Graphing the composition of twin prime summands vs. an even number (greater than 4) used to generate them, should result in the famous Goldbach's Comet plot.

I struggled with the makelist() command, using an IFTE() construct, but I got stuck on the "else" clause, thinking I wanted to add any twin primes, to the list, but nothing otherwise. No success there.
