Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100750, here are decompositions:

3 + 100747 = 100750
17 + 100733 = 100750
47 + 100703 = 100750
101 + 100649 = 100750
137 + 100613 = 100750
191 + 100559 = 100750
227 + 100523 = 100750
233 + 100517 = 100750

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 100,750 and was likely granted around 1870.

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