Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673640, here are decompositions:
- 29 + 8673611 = 8673640
- 47 + 8673593 = 8673640
- 71 + 8673569 = 8673640
- 251 + 8673389 = 8673640
- 263 + 8673377 = 8673640
- 281 + 8673359 = 8673640
- 293 + 8673347 = 8673640
- 347 + 8673293 = 8673640
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 8,673,640 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
