Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105028, here are decompositions:

5 + 105023 = 105028
29 + 104999 = 105028
41 + 104987 = 105028
137 + 104891 = 105028
149 + 104879 = 105028
179 + 104849 = 105028
197 + 104831 = 105028
227 + 104801 = 105028

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 105.028 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.
