Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671612, here are decompositions:
- 23 + 8671589 = 8671612
- 29 + 8671583 = 8671612
- 101 + 8671511 = 8671612
- 113 + 8671499 = 8671612
- 149 + 8671463 = 8671612
- 251 + 8671361 = 8671612
- 281 + 8671331 = 8671612
- 419 + 8671193 = 8671612
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 8,671,612 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
