Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158346, here are decompositions:

5 + 158341 = 158346
17 + 158329 = 158346
43 + 158303 = 158346
53 + 158293 = 158346
103 + 158243 = 158346
113 + 158233 = 158346
137 + 158209 = 158346
157 + 158189 = 158346

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 158,346 and was likely granted around 1873.

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