Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671320, here are decompositions:
- 13 + 8671307 = 8671320
- 29 + 8671291 = 8671320
- 71 + 8671249 = 8671320
- 89 + 8671231 = 8671320
- 101 + 8671219 = 8671320
- 127 + 8671193 = 8671320
- 173 + 8671147 = 8671320
- 193 + 8671127 = 8671320
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 8,671,320 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
