Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100726, here are decompositions:
- 23 + 100703 = 100726
- 53 + 100673 = 100726
- 113 + 100613 = 100726
- 167 + 100559 = 100726
- 179 + 100547 = 100726
- 233 + 100493 = 100726
- 257 + 100469 = 100726
- 347 + 100379 = 100726
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 100,726 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
