Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667458, here are decompositions:

31 + 8667427 = 8667458
109 + 8667349 = 8667458
139 + 8667319 = 8667458
157 + 8667301 = 8667458
307 + 8667151 = 8667458
337 + 8667121 = 8667458
379 + 8667079 = 8667458
577 + 8666881 = 8667458

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 8 667 458 and was likely granted around 2014.

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

Federal Reserve

United States Government

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
