    Loops are very unnecessary in this problem, here is the more elegant way

    a=int(raw_input(''))
for i in range(0,a):
    n=(int(raw_input('')))
    if n%3==0 and n!=0:
        print n*str(5)
    elif n%3==1 and n>=10:
        print (n-10)*str(5)+10*str(3)
    elif n%3==2 and n>=5:
        print (n-5)*str(5)+5*str(3)
    else:
        print '-1'
