Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111120, here are decompositions:

11 + 111109 = 111120
17 + 111103 = 111120
29 + 111091 = 111120
67 + 111053 = 111120
71 + 111049 = 111120
89 + 111031 = 111120
131 + 110989 = 111120
151 + 110969 = 111120

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 111,120 and was likely granted around 1871.

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