Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105040, here are decompositions:
- 3 + 105037 = 105040
- 17 + 105023 = 105040
- 41 + 104999 = 105040
- 53 + 104987 = 105040
- 107 + 104933 = 105040
- 149 + 104891 = 105040
- 191 + 104849 = 105040
- 239 + 104801 = 105040
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.154.80.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105.040 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
