Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669870, here are decompositions:

103 + 8669767 = 8669870
199 + 8669671 = 8669870
241 + 8669629 = 8669870
277 + 8669593 = 8669870
541 + 8669329 = 8669870
577 + 8669293 = 8669870
619 + 8669251 = 8669870
631 + 8669239 = 8669870

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 8 669 870 and was likely granted around 2014.

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