Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158310, here are decompositions:

7 + 158303 = 158310
17 + 158293 = 158310
41 + 158269 = 158310
67 + 158243 = 158310
79 + 158231 = 158310
83 + 158227 = 158310
101 + 158209 = 158310
109 + 158201 = 158310

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 158,310 and was likely granted around 1873.

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