Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641504, here are decompositions:
- 71 + 8641433 = 8641504
- 83 + 8641421 = 8641504
- 173 + 8641331 = 8641504
- 257 + 8641247 = 8641504
- 293 + 8641211 = 8641504
- 317 + 8641187 = 8641504
- 593 + 8640911 = 8641504
- 617 + 8640887 = 8641504
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 8,641,504 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
