Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509408, here are decompositions:

19 + 509389 = 509408
79 + 509329 = 509408
127 + 509281 = 509408
181 + 509227 = 509408
271 + 509137 = 509408
307 + 509101 = 509408
337 + 509071 = 509408
421 + 508987 = 509408

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 509,408 and was likely granted around 1893.

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