Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500900, here are decompositions:

13 + 500887 = 500900
19 + 500881 = 500900
61 + 500839 = 500900
109 + 500791 = 500900
181 + 500719 = 500900
223 + 500677 = 500900
229 + 500671 = 500900
271 + 500629 = 500900

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 500,900 and was likely granted around 1893.

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