Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111664, here are decompositions:
- 5 + 111659 = 111664
- 11 + 111653 = 111664
- 23 + 111641 = 111664
- 41 + 111623 = 111664
- 53 + 111611 = 111664
- 71 + 111593 = 111664
- 83 + 111581 = 111664
- 131 + 111533 = 111664
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 111,664 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
