Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512654, here are decompositions:

13 + 512641 = 512654
61 + 512593 = 512654
73 + 512581 = 512654
151 + 512503 = 512654
157 + 512497 = 512654
211 + 512443 = 512654
367 + 512287 = 512654
487 + 512167 = 512654

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 512,654 and was likely granted around 1893.

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