Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675640, here are decompositions:
- 19 + 8675621 = 8675640
- 67 + 8675573 = 8675640
- 131 + 8675509 = 8675640
- 137 + 8675503 = 8675640
- 167 + 8675473 = 8675640
- 191 + 8675449 = 8675640
- 199 + 8675441 = 8675640
- 227 + 8675413 = 8675640
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 8,675,640 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
