Given a list of integers, some of which may be negative, extract the pair that sums to the largest number.

a = t[0]
b = t[1]
max = a + b
for i in range(1,len(t))
        ta = t[i]
        for j in range(i+1,len(t))
                tb = t[j]
                if ta + tb > max
                        a = ta
                        b = tb

print a,b
