Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501000, here are decompositions:

23 + 500977 = 501000
43 + 500957 = 501000
47 + 500953 = 501000
53 + 500947 = 501000
67 + 500933 = 501000
79 + 500921 = 501000
89 + 500911 = 501000
109 + 500891 = 501000

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 501,000 and was likely granted around 1893.

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