Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168154, here are decompositions:

3 + 168151 = 168154
11 + 168143 = 168154
71 + 168083 = 168154
83 + 168071 = 168154
131 + 168023 = 168154
167 + 167987 = 168154
263 + 167891 = 168154
281 + 167873 = 168154

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 168,154 and was likely granted around 1874.

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