Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111530, here are decompositions:

37 + 111493 = 111530
43 + 111487 = 111530
103 + 111427 = 111530
157 + 111373 = 111530
193 + 111337 = 111530
229 + 111301 = 111530
277 + 111253 = 111530
313 + 111217 = 111530

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 111,530 and was likely granted around 1871.

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