Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008512, here are decompositions:

13 + 1008499 = 1008512
19 + 1008493 = 1008512
61 + 1008451 = 1008512
79 + 1008433 = 1008512
103 + 1008409 = 1008512
139 + 1008373 = 1008512
181 + 1008331 = 1008512
283 + 1008229 = 1008512

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 1,008,512 and was likely granted around 1911.

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