Faber, incidentally, as part of its promotion for the book, is offering one million dollars to anyone who can prove Goldbach's Conjecture within the next two years.
William Kneale has argued that Goldbach's conjecture (that every even number greater than two is the sum of two primes) disproves the conceivability thesis, since we can conceive of both the conjecture and its negation being true, although one of these must be necessarily false.
Now Goldbach's conjecture that all even numbers beyond 4 are sums of two odd primes has as a consequence that every odd number is a sum of no more than thre odd primes ('little Goldbach').
Every mathematician is convinced that no such number exists and that Goldbach's conjecture is true.
