Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100766, here are decompositions:
- 19 + 100747 = 100766
- 67 + 100699 = 100766
- 73 + 100693 = 100766
- 97 + 100669 = 100766
- 157 + 100609 = 100766
- 229 + 100537 = 100766
- 283 + 100483 = 100766
- 307 + 100459 = 100766
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 100,766 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
