factor-like output


I wrote a function for factorization of binomial coefficients. I want it to output result as t_MAT, just like factor().
And I can't figure out how to make it.
My code uses forprime for primes in some range and determines exponents of prime factors. Then it stores prime and its exponent as a vector, which I intend to append to resulting factorization matrix:

   \\ ... there goes the logic of checking prime and determination of its exponent
   v = [p, p_e];
return factors;   

I need to add vector rows to matrix dynamically, but if I make something like that:

    v1=[1, 2]
    v2=[3, 4]

m becomes [3, 4], missing first vector.
On the other hand, matrix() doesn't allow adding values dynamically.
Please help.

Best regards,
