Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161050, here are decompositions:

3 + 161047 = 161050
11 + 161039 = 161050
17 + 161033 = 161050
41 + 161009 = 161050
53 + 160997 = 161050
83 + 160967 = 161050
167 + 160883 = 161050
173 + 160877 = 161050

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 161,050 and was likely granted around 1874.

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