Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100146, here are decompositions:

17 + 100129 = 100146
37 + 100109 = 100146
43 + 100103 = 100146
89 + 100057 = 100146
97 + 100049 = 100146
103 + 100043 = 100146
127 + 100019 = 100146
157 + 99989 = 100146

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 100,146 and was likely granted around 1870.

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