Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673440, here are decompositions:
- 7 + 8673433 = 8673440
- 19 + 8673421 = 8673440
- 67 + 8673373 = 8673440
- 79 + 8673361 = 8673440
- 241 + 8673199 = 8673440
- 283 + 8673157 = 8673440
- 313 + 8673127 = 8673440
- 331 + 8673109 = 8673440
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 8,673,440 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
