Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163000, here are decompositions:

3 + 162997 = 163000
11 + 162989 = 163000
29 + 162971 = 163000
53 + 162947 = 163000
83 + 162917 = 163000
179 + 162821 = 163000
251 + 162749 = 163000
269 + 162731 = 163000

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 163,000 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
