Given m, n  2, we prove that, for sufficiently large y, the sum 1^n +···+ y^n is not a product of m consecutive integers. We also prove that for m ≠ n we have 1^m +···+ x^m ≠ 1^n +···+ y^n, provided x, y are sufficiently large. Among other auxiliary facts, we show that Bernoulli polynomials of odd index are indecomposable, and those of even index are ‘almost’ indecomposable, a result of independent interest.

Keywords: Bernoulli polynomials; Diophantine equations; indecomposable polynomials; power sums; products of consecutive integers
