Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505910, here are decompositions:

3 + 505907 = 505910
43 + 505867 = 505910
151 + 505759 = 505910
199 + 505711 = 505910
241 + 505669 = 505910
271 + 505639 = 505910
277 + 505633 = 505910
337 + 505573 = 505910

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 505,910 and was likely granted around 1893.

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