Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664448, here are decompositions:

17 + 8664431 = 8664448
29 + 8664419 = 8664448
59 + 8664389 = 8664448
71 + 8664377 = 8664448
131 + 8664317 = 8664448
137 + 8664311 = 8664448
461 + 8663987 = 8664448
479 + 8663969 = 8664448

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 8,664,448 and was likely granted around 2014.

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