Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100190, here are decompositions:

7 + 100183 = 100190
37 + 100153 = 100190
61 + 100129 = 100190
199 + 99991 = 100190
229 + 99961 = 100190
283 + 99907 = 100190
313 + 99877 = 100190
331 + 99859 = 100190

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 100,190 and was likely granted around 1870.

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