Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680820, here are decompositions:

7 + 8680813 = 8680820
19 + 8680801 = 8680820
67 + 8680753 = 8680820
79 + 8680741 = 8680820
97 + 8680723 = 8680820
103 + 8680717 = 8680820
151 + 8680669 = 8680820
277 + 8680543 = 8680820

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 8,680,820 and was likely granted around 2014.

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