Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673620, here are decompositions:

19 + 8673601 = 8673620
73 + 8673547 = 8673620
103 + 8673517 = 8673620
157 + 8673463 = 8673620
199 + 8673421 = 8673620
349 + 8673271 = 8673620
421 + 8673199 = 8673620
433 + 8673187 = 8673620

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 8,673,620 and was likely granted around 2014.

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