Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105002, here are decompositions:
- 3 + 104999 = 105002
- 31 + 104971 = 105002
- 43 + 104959 = 105002
- 151 + 104851 = 105002
- 199 + 104803 = 105002
- 223 + 104779 = 105002
- 229 + 104773 = 105002
- 241 + 104761 = 105002
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105,002 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
