Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105100, here are decompositions:

3 + 105097 = 105100
29 + 105071 = 105100
101 + 104999 = 105100
113 + 104987 = 105100
167 + 104933 = 105100
251 + 104849 = 105100
269 + 104831 = 105100
311 + 104789 = 105100

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 105.100 and was likely granted around 1870.

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