Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008630, here are decompositions:

13 + 1008617 = 1008630
17 + 1008613 = 1008630
19 + 1008611 = 1008630
23 + 1008607 = 1008630
41 + 1008589 = 1008630
43 + 1008587 = 1008630
59 + 1008571 = 1008630
67 + 1008563 = 1008630

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 1,008,630 and was likely granted around 1911.

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