Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681722, here are decompositions:

29 + 8681693 = 8681722
53 + 8681669 = 8681722
59 + 8681663 = 8681722
83 + 8681639 = 8681722
173 + 8681549 = 8681722
233 + 8681489 = 8681722
239 + 8681483 = 8681722
293 + 8681429 = 8681722

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 8,681,722 and was likely granted around 2014.

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