Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105900, here are decompositions:
- 17 + 105883 = 105900
- 29 + 105871 = 105900
- 37 + 105863 = 105900
- 71 + 105829 = 105900
- 83 + 105817 = 105900
- 131 + 105769 = 105900
- 139 + 105761 = 105900
- 149 + 105751 = 105900
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.157.172.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105.900 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
