Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500490, here are decompositions:

7 + 500483 = 500490
17 + 500473 = 500490
19 + 500471 = 500490
31 + 500459 = 500490
47 + 500443 = 500490
59 + 500431 = 500490
73 + 500417 = 500490
97 + 500393 = 500490

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 500,490 and was likely granted around 1893.

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