Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108642, here are decompositions:
- 5 + 108637 = 108642
- 11 + 108631 = 108642
- 71 + 108571 = 108642
- 89 + 108553 = 108642
- 101 + 108541 = 108642
- 109 + 108533 = 108642
- 113 + 108529 = 108642
- 139 + 108503 = 108642
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 108,642 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
