Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113666, here are decompositions:
- 19 + 113647 = 113666
- 43 + 113623 = 113666
- 109 + 113557 = 113666
- 127 + 113539 = 113666
- 199 + 113467 = 113666
- 229 + 113437 = 113666
- 283 + 113383 = 113666
- 307 + 113359 = 113666
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 113,666 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
