Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530440, here are decompositions:

11 + 530429 = 530440
47 + 530393 = 530440
101 + 530339 = 530440
107 + 530333 = 530440
137 + 530303 = 530440
173 + 530267 = 530440
179 + 530261 = 530440
191 + 530249 = 530440

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 530,440 and was likely granted around 1894.

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