Well 4 and 10's remainder on division by 6 is the same so really comes down to primes that have only 1,2,3,0 in the digits of course.

We get examples: 3 and 5 lead to 3(3)+1=10, 3(5)+1=16, then both fail to 5, and 8 which have difference 3. using that pattern again we can predict 7 will go to 11 as that's 3 away from 8. We then use...

guess I don't see why algebra alone couldn't finish most of them off 3 mod 16 came the fact that 6k+5 needs to be 5 modulo 8 to have more divisions by 2 to follow to lower the number itself .
