I finally decided to use a graph that had the odd numbers from 1 to 49 in the top row. I the second row, 51 to 99. I continued down to the last row ending in 349. After marking down all the composites of 3, down to 51, I went to 3 on the top row. Dropping down to the next row (essentially making it 53 and subtracting 2, I arrived at 51, 3*17. at 15 +50 -2, I arrived at 63. Every composite of 3 was add 48, or add 54 to go the other way. The 7 composites were add 42, or add 56 for the direction you want to go. This ran true for my graph up to 349. If the top row is changed to 1 to 99, 1 to 149,or higher, the pattern for each prime composite changes. Ex. 3 + 100= 103 +2 =105. Useless information, but interesting.

The problem with trying to find a pattern for the prime numbers is that everyone leaves the even numbers on the "sieve". I finally hit on the idea to leave out the even numbers and only list the odd numbers on my "sieve". I had to leave the  5 composites in the list since there are four numbers between 3 and 7 and two between 1 and 3 and two between 7 and 9. The results were very interesting. Got to go to work. I will try to explain later.

I have an idea that might help you make a little more sense of the prime pattern. If you are interestedlet me know. I have tried many times to make sense of the same problem.

I still remember how interested I was in school 60 years ago. When the class started to learn reading and arithmetic, I was hooked. When I got to the higher math, I couldn't understand most of it. I still do elementary math to keep the mind sharp. I am interested in the prime numbers , trying to find a pattern. I love a good puzzle! So I have come here to ask a few questions and some things I have found, if anyone is interested.
