Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943540, here are decompositions:

29 + 943511 = 943540
41 + 943499 = 943540
131 + 943409 = 943540
137 + 943403 = 943540
167 + 943373 = 943540
173 + 943367 = 943540
197 + 943343 = 943540
233 + 943307 = 943540

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 943,540 and was likely granted around 1909.

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