Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101668, here are decompositions:
- 5 + 101663 = 101668
- 41 + 101627 = 101668
- 107 + 101561 = 101668
- 131 + 101537 = 101668
- 137 + 101531 = 101668
- 167 + 101501 = 101668
- 179 + 101489 = 101668
- 191 + 101477 = 101668
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 101,668 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
