Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105066, here are decompositions:
- 29 + 105037 = 105066
- 43 + 105023 = 105066
- 47 + 105019 = 105066
- 67 + 104999 = 105066
- 79 + 104987 = 105066
- 107 + 104959 = 105066
- 113 + 104953 = 105066
- 149 + 104917 = 105066
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105,066 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
