Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111090, here are decompositions:

37 + 111053 = 111090
41 + 111049 = 111090
47 + 111043 = 111090
59 + 111031 = 111090
61 + 111029 = 111090
101 + 110989 = 111090
113 + 110977 = 111090
139 + 110951 = 111090

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 111,090 and was likely granted around 1871.

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