Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509100, here are decompositions:

13 + 509087 = 509100
29 + 509071 = 509100
37 + 509063 = 509100
47 + 509053 = 509100
73 + 509027 = 509100
113 + 508987 = 509100
127 + 508973 = 509100
131 + 508969 = 509100

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 509,100 and was likely granted around 1893.

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