Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126626, here are decompositions:
- 13 + 126613 = 126626
- 43 + 126583 = 126626
- 79 + 126547 = 126626
- 109 + 126517 = 126626
- 127 + 126499 = 126626
- 139 + 126487 = 126626
- 193 + 126433 = 126626
- 229 + 126397 = 126626
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 126,626 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
