Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158900, here are decompositions:

19 + 158881 = 158900
37 + 158863 = 158900
97 + 158803 = 158900
109 + 158791 = 158900
139 + 158761 = 158900
151 + 158749 = 158900
283 + 158617 = 158900
337 + 158563 = 158900

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 158,900 and was likely granted around 1873.

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