Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126752, here are decompositions:
- 13 + 126739 = 126752
- 19 + 126733 = 126752
- 61 + 126691 = 126752
- 139 + 126613 = 126752
- 151 + 126601 = 126752
- 211 + 126541 = 126752
- 271 + 126481 = 126752
- 331 + 126421 = 126752
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 126,752 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
