Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621000, here are decompositions:

7 + 8620993 = 8621000
103 + 8620897 = 8621000
127 + 8620873 = 8621000
139 + 8620861 = 8621000
277 + 8620723 = 8621000
313 + 8620687 = 8621000
337 + 8620663 = 8621000
379 + 8620621 = 8621000

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 8,621,000 and was likely granted around 2013.

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