Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105404, here are decompositions:

3 + 105401 = 105404
7 + 105397 = 105404
31 + 105373 = 105404
37 + 105367 = 105404
43 + 105361 = 105404
67 + 105337 = 105404
73 + 105331 = 105404
127 + 105277 = 105404

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 105.404 and was likely granted around 1870.

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