In or out?

Let the following pseudo-random generator:

static long seed = 641;
static long FastRandom()
{
	seed = (214013 * seed + 2531011) % 2147483647;
	return seed;
}

We consider the first 60000 values of this generator modulo 1000 as the coordinates of 10000 triangles:
$T_1=(344,302)(678,941)(488,674)$
$T_2=(107,545)(964,568)(808,239)$
$\dots$
$T_{10000}=(862,679)(571,263)(391,426)$

How many times is the point (499,499) inside one of these triangles?
