Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680400, here are decompositions:

31 + 8680369 = 8680400
73 + 8680327 = 8680400
97 + 8680303 = 8680400
103 + 8680297 = 8680400
151 + 8680249 = 8680400
181 + 8680219 = 8680400
199 + 8680201 = 8680400
229 + 8680171 = 8680400

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 8.680.400 and was likely granted around 2014.

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