Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105690, here are decompositions:
- 7 + 105683 = 105690
- 17 + 105673 = 105690
- 23 + 105667 = 105690
- 37 + 105653 = 105690
- 41 + 105649 = 105690
- 71 + 105619 = 105690
- 83 + 105607 = 105690
- 89 + 105601 = 105690
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 105 690 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
