Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671864, here are decompositions:
- 53 + 8671811 = 8671864
- 167 + 8671697 = 8671864
- 233 + 8671631 = 8671864
- 281 + 8671583 = 8671864
- 347 + 8671517 = 8671864
- 353 + 8671511 = 8671864
- 401 + 8671463 = 8671864
- 503 + 8671361 = 8671864
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 8,671,864 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
