Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685142, here are decompositions:

101 + 8685041 = 8685142
239 + 8684903 = 8685142
269 + 8684873 = 8685142
281 + 8684861 = 8685142
311 + 8684831 = 8685142
353 + 8684789 = 8685142
359 + 8684783 = 8685142
383 + 8684759 = 8685142

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 8,685,142 and was likely granted around 2014.

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