Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681654, here are decompositions:

31 + 8681623 = 8681654
67 + 8681587 = 8681654
151 + 8681503 = 8681654
181 + 8681473 = 8681654
277 + 8681377 = 8681654
313 + 8681341 = 8681654
337 + 8681317 = 8681654
367 + 8681287 = 8681654

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 8 681 654 and was likely granted around 2014.

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