Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100774, here are decompositions:
- 5 + 100769 = 100774
- 41 + 100733 = 100774
- 71 + 100703 = 100774
- 101 + 100673 = 100774
- 227 + 100547 = 100774
- 251 + 100523 = 100774
- 257 + 100517 = 100774
- 263 + 100511 = 100774
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 100,774 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
