Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104728, here are decompositions:

5 + 104723 = 104728
11 + 104717 = 104728
17 + 104711 = 104728
47 + 104681 = 104728
89 + 104639 = 104728
131 + 104597 = 104728
149 + 104579 = 104728
167 + 104561 = 104728

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 104,728 and was likely granted around 1870.

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