Please Confirm 369,569

[NotLKH]

Are there 369569 subsets of 6 numbers that add to 150, from
a set of 61 numbers, range = 1 to 61?

ie...
Given:

Dim MySourceArr() As Integer
ReDim MySourceArr(60)
For MyI = 0 To 60
    MySourceArr(MyI) = MyI + 1
Next MyI

and:

Dim My4_arr() As Integer
ReDim My4_arr(5)

How many combinations of 61 elements, taken 6 at a time add to 150, if the 61 elements are the numbers 1 thru 61?

I've got an app that calculates 369569 of them over 71 seconds, and I'm wondering if it is correct?
