Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158500, here are decompositions:

11 + 158489 = 158500
71 + 158429 = 158500
107 + 158393 = 158500
137 + 158363 = 158500
149 + 158351 = 158500
197 + 158303 = 158500
239 + 158261 = 158500
257 + 158243 = 158500

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 158,500 and was likely granted around 1873.

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