Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663520, here are decompositions:

11 + 8663509 = 8663520
13 + 8663507 = 8663520
17 + 8663503 = 8663520
23 + 8663497 = 8663520
53 + 8663467 = 8663520
59 + 8663461 = 8663520
79 + 8663441 = 8663520
83 + 8663437 = 8663520

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 8,663,520 and was likely granted around 2014.

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