    answer = []
    nPr = permutations(numbers, 2)
    
    for i in list(nPr):
        if sum(i) in answer:
            continue
        answer.append(sum(i))

from itertools import combinations

def solution(numbers):
    answer = []
    l = list(combinations(numbers, 2))

    for i in l:
        answer.append(i[0]+i[1])
    answer = list(set(answer))
    answer.sort()

    return answer
