Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105008, here are decompositions:

37 + 104971 = 105008
61 + 104947 = 105008
97 + 104911 = 105008
139 + 104869 = 105008
157 + 104851 = 105008
181 + 104827 = 105008
229 + 104779 = 105008
307 + 104701 = 105008

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 105 008 and was likely granted around 1870.

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