Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670830, here are decompositions:

19 + 8670811 = 8670830
79 + 8670751 = 8670830
127 + 8670703 = 8670830
151 + 8670679 = 8670830
163 + 8670667 = 8670830
193 + 8670637 = 8670830
211 + 8670619 = 8670830
241 + 8670589 = 8670830

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 8,670,830 and was likely granted around 2014.

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