Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518100, here are decompositions:

17 + 518083 = 518100
41 + 518059 = 518100
43 + 518057 = 518100
53 + 518047 = 518100
83 + 518017 = 518100
101 + 517999 = 518100
109 + 517991 = 518100
151 + 517949 = 518100

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 518,100 and was likely granted around 1894.

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