Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685278, here are decompositions:

67 + 8685211 = 8685278
79 + 8685199 = 8685278
127 + 8685151 = 8685278
331 + 8684947 = 8685278
337 + 8684941 = 8685278
367 + 8684911 = 8685278
457 + 8684821 = 8685278
691 + 8684587 = 8685278

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 8,685,278 and was likely granted around 2014.

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