Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105730, here are decompositions:

3 + 105727 = 105730
29 + 105701 = 105730
47 + 105683 = 105730
167 + 105563 = 105730
173 + 105557 = 105730
197 + 105533 = 105730
227 + 105503 = 105730
239 + 105491 = 105730

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 105 730 and was likely granted around 1870.

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