Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540400, here are decompositions:

11 + 540389 = 540400
17 + 540383 = 540400
23 + 540377 = 540400
53 + 540347 = 540400
131 + 540269 = 540400
149 + 540251 = 540400
167 + 540233 = 540400
197 + 540203 = 540400

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 540,400 and was likely granted around 1894.

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