Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100564, here are decompositions:
- 5 + 100559 = 100564
- 17 + 100547 = 100564
- 41 + 100523 = 100564
- 47 + 100517 = 100564
- 53 + 100511 = 100564
- 71 + 100493 = 100564
- 173 + 100391 = 100564
- 251 + 100313 = 100564
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 100,564 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
