Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669168, here are decompositions:

61 + 8669107 = 8669168
97 + 8669071 = 8669168
127 + 8669041 = 8669168
271 + 8668897 = 8669168
331 + 8668837 = 8669168
337 + 8668831 = 8669168
367 + 8668801 = 8669168
457 + 8668711 = 8669168

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 8,669,168 and was likely granted around 2014.

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