Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540040, here are decompositions:

47 + 539993 = 540040
191 + 539849 = 540040
197 + 539843 = 540040
257 + 539783 = 540040
311 + 539729 = 540040
317 + 539723 = 540040
353 + 539687 = 540040
401 + 539639 = 540040

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 540,040 and was likely granted around 1894.

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