Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105648, here are decompositions:
- 29 + 105619 = 105648
- 41 + 105607 = 105648
- 47 + 105601 = 105648
- 107 + 105541 = 105648
- 131 + 105517 = 105648
- 139 + 105509 = 105648
- 149 + 105499 = 105648
- 157 + 105491 = 105648
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.156.176.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105.648 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
