Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126504, here are decompositions:
- 5 + 126499 = 126504
- 11 + 126493 = 126504
- 13 + 126491 = 126504
- 17 + 126487 = 126504
- 23 + 126481 = 126504
- 31 + 126473 = 126504
- 43 + 126461 = 126504
- 47 + 126457 = 126504
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 126,504 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
