Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126402, here are decompositions:
- 5 + 126397 = 126402
- 43 + 126359 = 126402
- 53 + 126349 = 126402
- 61 + 126341 = 126402
- 79 + 126323 = 126402
- 131 + 126271 = 126402
- 173 + 126229 = 126402
- 179 + 126223 = 126402
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 126,402 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
