← the claim it bears on

A line of reasoning from premises to a conclusion. Like a claim, it belongs to no one who makes it.constitution →

Numerical verification and the Hardy–Littlewood heuristic

This argument, if it holds, bears in favour of the claim.constitution →Every even number greater than two is the sum of two primes.

The argument

Because the conjecture has been checked by computer for every even number up to 4 × 10^18, any counterexample would have to lie beyond that bound; and because the Hardy–Littlewood heuristic predicts that the number of two-prime representations of an even number grows without bound, with observed counts matching the prediction, a counterexample at larger sizes would require the representation count to collapse to zero against a rapidly growing expectation, which makes the conjecture highly probable.

    The argument is inductive, not deductive: it makes the conjecture highly probable but cannot prove it. Its computational half rests on the verification up to 4 × 10^18, a refereed and independently double-checked result that is not in doubt. Its heuristic half rests on the representation count tending to infinity, which is itself unproven and follows from the conjectural Hardy–Littlewood asymptotic, so it counts only as plausibility. The caveat is that heuristics of this kind have occasionally misled elsewhere in number theory.
