Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158300, here are decompositions:

7 + 158293 = 158300
31 + 158269 = 158300
67 + 158233 = 158300
73 + 158227 = 158300
139 + 158161 = 158300
157 + 158143 = 158300
223 + 158077 = 158300
229 + 158071 = 158300

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 158,300 and was likely granted around 1873.

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