Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687506, here are decompositions:

29 + 8687477 = 8687506
53 + 8687453 = 8687506
83 + 8687423 = 8687506
137 + 8687369 = 8687506
197 + 8687309 = 8687506
257 + 8687249 = 8687506
293 + 8687213 = 8687506
389 + 8687117 = 8687506

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 8,687,506 and was likely granted around 2014.

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