How can I find the records that are NOT IN the list

[Daevid Vincent]

I have an "IN()" list of 107 IDs (PK) out of about 6000 possible.

I do this query and I get 105 rows back. 

I want to know which two [107 - 105 = 2] of the IDs in the "IN()" list are
absent?

# 105 rows 
SELECT count(*)
FROM mytable  
WHERE id IN (11704, 10144, 11842, 11299, 11192, 11563, 11378, 10343, 10752,
10626, 11916, 11456, 11813, 11337, 10219, 11356, 11800, 10243, 10251, 11357,
11353, 11267, 12110, 200044, 11875, 11060, 10233, 10865, 10264, 10857,
10659, 10266, 10987, 11317, 11868, 10858, 11087, 11088, 10260, 11321, 11350,
10247, 10258, 10248, 11232, 10588, 11086, 11828, 10055, 11347, 10278, 11349,
10261, 11499, 11351, 11316, 12284, 12240, 12265, 11340, 10708, 11041, 11853,
12255, 11507, 11788, 10067, 10888, 11875, 11333, 10867, 10938, 11030, 10654,
10538, 10918, 11068, 11237, 11060, 10127, 10495, 10035, 10294, 10173, 10098,
10282, 10383, 10049, 10076, 10277, 10106, 10541, 10176, 10131, 10252, 11051,
