Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105072, here are decompositions:
- 41 + 105031 = 105072
- 53 + 105019 = 105072
- 73 + 104999 = 105072
- 101 + 104971 = 105072
- 113 + 104959 = 105072
- 139 + 104933 = 105072
- 181 + 104891 = 105072
- 193 + 104879 = 105072
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.154.112.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105.072 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
