Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664642, here are decompositions:

29 + 8664613 = 8664642
61 + 8664581 = 8664642
83 + 8664559 = 8664642
89 + 8664553 = 8664642
113 + 8664529 = 8664642
191 + 8664451 = 8664642
211 + 8664431 = 8664642
223 + 8664419 = 8664642

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 8,664,642 and was likely granted around 2014.

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