Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126684, here are decompositions:
- 31 + 126653 = 126684
- 43 + 126641 = 126684
- 53 + 126631 = 126684
- 71 + 126613 = 126684
- 73 + 126611 = 126684
- 83 + 126601 = 126684
- 101 + 126583 = 126684
- 137 + 126547 = 126684
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 126,684 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
