Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703856, here are decompositions:

3 + 8703853 = 8703856
23 + 8703833 = 8703856
113 + 8703743 = 8703856
137 + 8703719 = 8703856
197 + 8703659 = 8703856
233 + 8703623 = 8703856
263 + 8703593 = 8703856
467 + 8703389 = 8703856

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 8,703,856 and was likely granted around 2014.

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