Well, could be
Code:
if input == 9423549 {
    output = 433827
}

or
Code:
output = input - 8989722

or
Code:
output = (input - 313182) / 21

or
Code:
output = string(input[1], input[3], input[3], input[0] - 1, input[2], input [6] - 2)

or
Code:
output = reverse(reverse(input) - 8724915)

or
Code:
output = string(min(input[0], input[1]), (input[1] + input[2]) / 2, max(input[2], input[3]), input[3] + input[4], 2 * (input[4] - input[5]), input[6] - input[5] / 2)

or even
Code:
output = 433827

You need to post a few more examples.

I mean, if I asked how to get from "A" to "B", what would you (or anyone guess)?

But if I asked "A" to "B", "B" to "C", "C" to "D", "D" to "E", we all might figure out the pattern that would reasonably allow us to guess what "S" would translate to.
