Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126284, here are decompositions:
- 13 + 126271 = 126284
- 43 + 126241 = 126284
- 61 + 126223 = 126284
- 73 + 126211 = 126284
- 157 + 126127 = 126284
- 271 + 126013 = 126284
- 283 + 126001 = 126284
- 397 + 125887 = 126284
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 126,284 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
