Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104320, here are decompositions:

11 + 104309 = 104320
23 + 104297 = 104320
89 + 104231 = 104320
113 + 104207 = 104320
137 + 104183 = 104320
173 + 104147 = 104320
197 + 104123 = 104320
233 + 104087 = 104320

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 104,320 and was likely granted around 1870.

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

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.
