Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513000, here are decompositions:

11 + 512989 = 513000
23 + 512977 = 513000
41 + 512959 = 513000
71 + 512929 = 513000
73 + 512927 = 513000
79 + 512921 = 513000
83 + 512917 = 513000
97 + 512903 = 513000

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 513,000 and was likely granted around 1893.

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