Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663478, here are decompositions:

7 + 8663471 = 8663478
11 + 8663467 = 8663478
17 + 8663461 = 8663478
37 + 8663441 = 8663478
41 + 8663437 = 8663478
167 + 8663311 = 8663478
199 + 8663279 = 8663478
269 + 8663209 = 8663478

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 8,663,478 and was likely granted around 2014.

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