Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105280, here are decompositions:

3 + 105277 = 105280
11 + 105269 = 105280
17 + 105263 = 105280
29 + 105251 = 105280
41 + 105239 = 105280
53 + 105227 = 105280
107 + 105173 = 105280
113 + 105167 = 105280

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 105.280 and was likely granted around 1870.

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

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
