Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180112, here are decompositions:

41 + 180071 = 180112
59 + 180053 = 180112
89 + 180023 = 180112
113 + 179999 = 180112
131 + 179981 = 180112
173 + 179939 = 180112
263 + 179849 = 180112
293 + 179819 = 180112

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 180,112 and was likely granted around 1875.

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