Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105842, here are decompositions:

13 + 105829 = 105842
73 + 105769 = 105842
109 + 105733 = 105842
151 + 105691 = 105842
193 + 105649 = 105842
223 + 105619 = 105842
229 + 105613 = 105842
241 + 105601 = 105842

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 105.842 and was likely granted around 1870.

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