Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105112, here are decompositions:

5 + 105107 = 105112
41 + 105071 = 105112
89 + 105023 = 105112
113 + 104999 = 105112
179 + 104933 = 105112
233 + 104879 = 105112
263 + 104849 = 105112
281 + 104831 = 105112

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 105,112 and was likely granted around 1870.

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