Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112800, here are decompositions:

13 + 112787 = 112800
29 + 112771 = 112800
41 + 112759 = 112800
43 + 112757 = 112800
59 + 112741 = 112800
109 + 112691 = 112800
113 + 112687 = 112800
137 + 112663 = 112800

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 112,800 and was likely granted around 1871.

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