Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100066, here are decompositions:
- 17 + 100049 = 100066
- 23 + 100043 = 100066
- 47 + 100019 = 100066
- 137 + 99929 = 100066
- 227 + 99839 = 100066
- 233 + 99833 = 100066
- 257 + 99809 = 100066
- 347 + 99719 = 100066
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 100,066 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
