Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028630, here are decompositions:

13 + 1028617 = 1028630
61 + 1028569 = 1028630
73 + 1028557 = 1028630
151 + 1028479 = 1028630
157 + 1028473 = 1028630
193 + 1028437 = 1028630
241 + 1028389 = 1028630
313 + 1028317 = 1028630

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 1,028,630 and was likely granted around 1912.

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