Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500556, here are decompositions:

29 + 500527 = 500556
37 + 500519 = 500556
47 + 500509 = 500556
73 + 500483 = 500556
83 + 500473 = 500556
97 + 500459 = 500556
113 + 500443 = 500556
139 + 500417 = 500556

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 500,556 and was likely granted around 1893.

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