Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664240, here are decompositions:
- 17 + 8664223 = 8664240
- 47 + 8664193 = 8664240
- 59 + 8664181 = 8664240
- 83 + 8664157 = 8664240
- 131 + 8664109 = 8664240
- 197 + 8664043 = 8664240
- 271 + 8663969 = 8664240
- 281 + 8663959 = 8664240
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 8,664,240 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
