... Theorem. Every sufficiently large even integer n > 46 can be expressed as the sum of abundant numbers a and b thus: a + b = n. Proof. First we rewrite n = 2x (where x is some positive integer) as n = 20m+r, where r satisfies n ≡ r mod 20 and m = n−r 20 . If r = 0, then we’re done, we can simply set ...
