Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105948, here are decompositions:
- 5 + 105943 = 105948
- 19 + 105929 = 105948
- 41 + 105907 = 105948
- 131 + 105817 = 105948
- 179 + 105769 = 105948
- 181 + 105767 = 105948
- 197 + 105751 = 105948
- 257 + 105691 = 105948
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.157.220.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105.948 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
