Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179130, here are decompositions:

11 + 179119 = 179130
19 + 179111 = 179130
23 + 179107 = 179130
31 + 179099 = 179130
41 + 179089 = 179130
47 + 179083 = 179130
73 + 179057 = 179130
79 + 179051 = 179130

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 179,130 and was likely granted around 1875.

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