Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168830, here are decompositions:

61 + 168769 = 168830
157 + 168673 = 168830
199 + 168631 = 168830
229 + 168601 = 168830
271 + 168559 = 168830
307 + 168523 = 168830
331 + 168499 = 168830
349 + 168481 = 168830

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 168,830 and was likely granted around 1874.

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