Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709500, here are decompositions:

31 + 8709469 = 8709500
127 + 8709373 = 8709500
139 + 8709361 = 8709500
199 + 8709301 = 8709500
211 + 8709289 = 8709500
229 + 8709271 = 8709500
271 + 8709229 = 8709500
313 + 8709187 = 8709500

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 8,709,500 and was likely granted around 2014.

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