Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540190, here are decompositions:

3 + 540187 = 540190
11 + 540179 = 540190
17 + 540173 = 540190
23 + 540167 = 540190
41 + 540149 = 540190
71 + 540119 = 540190
89 + 540101 = 540190
149 + 540041 = 540190

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 540,190 and was likely granted around 1894.

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