Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102764, here are decompositions:
- 3 + 102761 = 102764
- 97 + 102667 = 102764
- 157 + 102607 = 102764
- 241 + 102523 = 102764
- 283 + 102481 = 102764
- 313 + 102451 = 102764
- 331 + 102433 = 102764
- 367 + 102397 = 102764
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 102,764 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
