Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126000, here are decompositions:
- 37 + 125963 = 126000
- 41 + 125959 = 126000
- 59 + 125941 = 126000
- 67 + 125933 = 126000
- 71 + 125929 = 126000
- 73 + 125927 = 126000
- 79 + 125921 = 126000
- 101 + 125899 = 126000
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 126,000 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
