Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105662, here are decompositions:
- 13 + 105649 = 105662
- 43 + 105619 = 105662
- 61 + 105601 = 105662
- 163 + 105499 = 105662
- 283 + 105379 = 105662
- 331 + 105331 = 105662
- 409 + 105253 = 105662
- 433 + 105229 = 105662
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.156.190.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105 662 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.
