We present deep SCUBA-2 450{mu}m imaging of the two GOODS fields, achieving a central rms of 1.14mJy for the GOODS-N and 1.86mJy for the GOODS-S. For each field, we give a catalog of >4{sigma} detections (79 and 16 sources, respectively). We construct the 450{mu}m number counts, finding excellent agreement with others from the literature. We match the 450{mu}m sources to 20cm data (both fields) and ALMA 870{mu}m data (GOODS-S) to gauge the accuracy of the 450{mu}m positions. We use the extensive redshift information available on the fields to test how well redshift can be estimated from simple flux ratios (450{mu}m/850{mu}m and 20cm/850{mu}m), finding tight correlations. We provide a catalog of candidate high-redshift submillimeter galaxies. We look for evolution in dust temperature with redshift by fitting the spectral energy distributions of the sources, but we do not find any significant redshift evolution after accounting for the far-infrared luminosity. We do not find evidence for the 450{mu}m selection picking out warmer sources than an 850{mu}m selection. We find that a 450 {mu}m-selected sample only adds low-redshift (z4{sigma}))
