Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681120, here are decompositions:

3 + 8681117 = 8681120
31 + 8681089 = 8681120
43 + 8681077 = 8681120
61 + 8681059 = 8681120
73 + 8681047 = 8681120
127 + 8680993 = 8681120
181 + 8680939 = 8681120
199 + 8680921 = 8681120

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 8,681,120 and was likely granted around 2014.

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