EDIT: As the answer has been found, the clues would have been:
1) An edit to the title to be "A Prime Example..."
2) Adding 19 to the beginning of the sequence
3) A link to an online calculator for finding prime factorials
4) The statement that the last clue just about summed it up

Bonus Question:
What can you choose as the starting number such that the pattern repeats itself forever?

I think I see a pattern in there, it only works in case one of your calculations is incorrect though.

The solution:

A = 255, B = 99462, C = 20802746

The incorrect transition:

99462 -> 2538, you forgot to mention 19024 in between.

The pattern:

Take a number, split it into its prime factors, add the square of each prime factor to arrive at the next number.
Example: 2538 is 2*3*3*3*47, adding the squares is 4+9+9+9+2209, next number is 2240.
