Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540180, here are decompositions:

7 + 540173 = 540180
13 + 540167 = 540180
23 + 540157 = 540180
31 + 540149 = 540180
41 + 540139 = 540180
59 + 540121 = 540180
61 + 540119 = 540180
79 + 540101 = 540180

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 540,180 and was likely granted around 1894.

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