Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681340, here are decompositions:

23 + 8681317 = 8681340
29 + 8681311 = 8681340
53 + 8681287 = 8681340
89 + 8681251 = 8681340
97 + 8681243 = 8681340
127 + 8681213 = 8681340
149 + 8681191 = 8681340
163 + 8681177 = 8681340

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 8,681,340 and was likely granted around 2014.

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