Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540250, here are decompositions:

17 + 540233 = 540250
47 + 540203 = 540250
71 + 540179 = 540250
83 + 540167 = 540250
101 + 540149 = 540250
131 + 540119 = 540250
149 + 540101 = 540250
257 + 539993 = 540250

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 540,250 and was likely granted around 1894.

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