Ok I've done some quick timings, it's faster than I remembered it:

numbers = [2, 4, 5, 8, 25]
target = 758

Average time to find
(1) best solution (in terms of length of repr): 0.0418s
(2) first solution: 0.00421s

(2.2GHz MacBook Pro, done with the timeit module)

(1) involves working out all possible calculations with the 6 numbers.
