Proof of goldbach's conjecture - from my grandpa
My grandpa (now deceased) was a mathematician from China who spent around a decade working on a proof for the goldbach conjecture. He believes that he proved it, and a succinct version of his proof was published at his local university in Tianjin & also can be found on the UBC archive. However, the people who reviewed his work didn't really understand what he was doing (I think he spent quite a few days working them through it, this was in the 80s by the way).
His original draft and everything is very very long (around 600 pages). I have a version of it I'm translating to English which is much shorter. I'm the only one in my family interested in what he did, and I want someone else in the area to read his work and see if it has any merit. I think he definitely would have made a few contributions, but given that he did this decades ago and my limited understanding of the conjecture itself, it would be best if someone could help me with this.
I have no idea who to ask or where to find the resources to help. I'm also in high school and have been doing this as a fun summer project, but I think it's worth asking on here anyway if anyone has any suggestions for this kind of stuff. Any help is appreciated!
