Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163430, here are decompositions:

13 + 163417 = 163430
19 + 163411 = 163430
37 + 163393 = 163430
67 + 163363 = 163430
79 + 163351 = 163430
103 + 163327 = 163430
109 + 163321 = 163430
181 + 163249 = 163430

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 163,430 and was likely granted around 1874.

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