Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105430, here are decompositions:

23 + 105407 = 105430
29 + 105401 = 105430
41 + 105389 = 105430
71 + 105359 = 105430
89 + 105341 = 105430
107 + 105323 = 105430
167 + 105263 = 105430
179 + 105251 = 105430

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 105.430 and was likely granted around 1870.

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