SML pls.

Goldbach's conjecture says that every positive even number greater than 2 is the sum of two prime numbers. Write an SML function goldbach that takes a single positive, even integer as its parameter and returns a list containing the two prime numbers that sum to the parameter. You may assume that the parameter is a positive, even integer. Examples:

goldbach(4000) would return [11, 3989] or [3989, 11]

goldbach(3818) would return [79, 3739] or [3739, 79]
