By way of background, see my previous Adjacent Ramsey Theorem:

Our last PA independence posting is at
http://www.cs.nyu.edu/pipermail/fom/2012-October/016753.html, which
opened up a new general theory of statements at the PA level,
incorporating the Adjacent Ramsey Theorem. It also contains a very
simple statements about surjective polynomials with integer
coefficients independent of PA (equivalent to the 2-consistency of PA)
- Here we present a stronger statement about polynomials without
assuming surjectivity, that is independent of PA.

POLYNOMIAL PREIMAGE THEOREM A. For all polynomials P:N^k into N^k
there exist n_1 < ... < n_k+1 such that P-1(n_1,...,n_k)) is contained
in P-1(n_2,...,n_k+1) - N^k.

POLYNOMIAL PREIMAGE THEOREM B. For all polynomials P:N^k into Z^k
there exist nonnegative n_1 < ... < n_k+1 such that P-1(n_1,...,n_k)
is contained in P-1(n_2,...,n_k+1) - N^k.

Here A - B = {x - y: x in A and y in B}.

THEOREM 1. PPT is provable in ACA' but not in PA. PPT implies
2-Con(PA) over EFA.
