Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126320, here are decompositions:
- 3 + 126317 = 126320
- 13 + 126307 = 126320
- 79 + 126241 = 126320
- 97 + 126223 = 126320
- 109 + 126211 = 126320
- 193 + 126127 = 126320
- 223 + 126097 = 126320
- 241 + 126079 = 126320
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 126,320 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
