Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510900, here are decompositions:

11 + 510889 = 510900
53 + 510847 = 510900
73 + 510827 = 510900
83 + 510817 = 510900
97 + 510803 = 510900
107 + 510793 = 510900
127 + 510773 = 510900
149 + 510751 = 510900

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 510,900 and was likely granted around 1893.

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