Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643024, here are decompositions:
- 11 + 8643013 = 8643024
- 73 + 8642951 = 8643024
- 97 + 8642927 = 8643024
- 113 + 8642911 = 8643024
- 127 + 8642897 = 8643024
- 163 + 8642861 = 8643024
- 167 + 8642857 = 8643024
- 251 + 8642773 = 8643024
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 8,643,024 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
