Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104200, here are decompositions:

17 + 104183 = 104200
53 + 104147 = 104200
113 + 104087 = 104200
167 + 104033 = 104200
179 + 104021 = 104200
191 + 104009 = 104200
197 + 104003 = 104200
233 + 103967 = 104200

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 104,200 and was likely granted around 1870.

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