Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158200, here are decompositions:

11 + 158189 = 158200
59 + 158141 = 158200
71 + 158129 = 158200
191 + 158009 = 158200
197 + 158003 = 158200
269 + 157931 = 158200
293 + 157907 = 158200
311 + 157889 = 158200

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 158,200 and was likely granted around 1873.

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