Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105728, here are decompositions:

37 + 105691 = 105728
61 + 105667 = 105728
79 + 105649 = 105728
109 + 105619 = 105728
127 + 105601 = 105728
199 + 105529 = 105728
211 + 105517 = 105728
229 + 105499 = 105728

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 105.728 and was likely granted around 1870.

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