Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105102, here are decompositions:
- 5 + 105097 = 105102
- 31 + 105071 = 105102
- 71 + 105031 = 105102
- 79 + 105023 = 105102
- 83 + 105019 = 105102
- 103 + 104999 = 105102
- 131 + 104971 = 105102
- 149 + 104953 = 105102
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.154.142.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105.102 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
