Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510240, here are decompositions:

7 + 510233 = 510240
13 + 510227 = 510240
23 + 510217 = 510240
37 + 510203 = 510240
41 + 510199 = 510240
61 + 510179 = 510240
83 + 510157 = 510240
103 + 510137 = 510240

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 510,240 and was likely granted around 1893.

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