OIM 2025 Problem 4

    Determine todos os pares de números primos (p,q)(p, q) com p>q>1p > q > 1, tais que

    (p−q−1)3+(p−q)3+⋯+(p−1)3+p3+(p+1)3+⋯+(p+q)3+(p+q+1)3=(3pq)2.(p - q - 1)^3 + (p - q)^3 + \cdots + (p - 1)^3 + p^3 + (p + 1)^3 + \cdots + (p + q)^3 + (p + q + 1)^3 = (3pq)^2.

    Note que o lado esquerdo da igualdade tem 2q+32q + 3 parcelas, as quais são cubos de números consecutivos.
