Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105012, here are decompositions:

13 + 104999 = 105012
41 + 104971 = 105012
53 + 104959 = 105012
59 + 104953 = 105012
79 + 104933 = 105012
101 + 104911 = 105012
163 + 104849 = 105012
181 + 104831 = 105012

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 105.012 and was likely granted around 1870.

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