Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118530, here are decompositions:

37 + 118493 = 118530
59 + 118471 = 118530
67 + 118463 = 118530
73 + 118457 = 118530
101 + 118429 = 118530
107 + 118423 = 118530
131 + 118399 = 118530
157 + 118373 = 118530

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 118,530 and was likely granted around 1871.

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