It looks like you are trying to find two prime numbers that add up to an even number x. Here's the corrected code:

b = []
c = []

for m in range(2, y+1):
    n = x - m
    e = m // 2
    f = n // 2
    for i in range(2, e+1):
        if m % i == 0:
            b.append(i)
    if len(b) < 1:
        for j in range(2, f+1):
            if n % j == 0:
                c.append(j)
        if len(c) < 1:
            print("The two prime numbers that add up to " + str(x) + " are " + str(m) + " and " + str(n))

Please note that the variables x and y need to be defined before this code block for it to work properly.
