Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111500, here are decompositions:

3 + 111497 = 111500
7 + 111493 = 111500
13 + 111487 = 111500
61 + 111439 = 111500
73 + 111427 = 111500
127 + 111373 = 111500
163 + 111337 = 111500
199 + 111301 = 111500

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 111,500 and was likely granted around 1871.

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